Q: A string of 20 identical Christmas tree lights?
A string of 20 identical Christmas tree lights are connected in series to a 120 V source. The string dissipates 82 W. a)What is the equivalent resistance of the light string? Answer in units of ­ohms. b)What is the resistance of a single light? Answer in units of ­ohms

A: Power = VI = V^2/R In series, resistances add, so each light contributes the same amount of resistance to the string. You should be able to do the rest from there.

Q: The Christmas Lights-Why did people use candles on Christmas trees to light up their tree? see details below.?
I read that thousands of years ago people used candles to light up their Christmas trees, I wanna know since they used candles, did the use of candles put the tree at risk of catching on fire? your answer may be as long as possible, the longer it is the more information I can take in my head to learn.

A: "Thousands of years ago" before the time of Jesus, people used flashlights tied to the branches. However in those days, the batteries were as bulky and as heavy as today's car batteries. One flashlight tied to a branch on each side of the tree. That did the job so well that no stand was needed. The batteries were powered by squirrels which ran in wheels inside. Candles were used when squirrels were not available. OR It was only 100 years ago candles were used to light trees. One story has it that Martin Luther, the one who began the Protestant Reformation in Germany, brought a tree home and put candles on it to simulate the stars shining through the branches that he had seen when walking through the woods. As late as 60 years ago, fire marshals were forbidding churches from using candles on trees because of the fire hazard. It doesn't take long for a tree to dry out and become susceptible to the slightest spark. The small Italian lights that are on most trees now, replaced the larger light bulbs because they generate less heat.

Q: Kitten won't leave the Christmas tree/lights alone!?
I love my five month kitten to death, but he's REALLY annoying me right now. I'm a first time cat owner, so I'm not used to the stubbornness/independence that cats are basically known for. Christmas is my favorite holiday, so of course, I decorated my place with a 7ft tall (artificial) Christmas tree, and some Christmas lights on it. Kitty LOVES climbing on the Christmas tree, chewing on the lights, wires, and ornaments, and there's basically nothing that will stop him. I'm worried for HIS safety, and I don't want any fires to start (remember what happened to the kitty on National Lampoon's Christmas vacation?) I've been spraying him consistently with water, and he'll stop for a few moments, but will come back minutes later. I've tried spraying the decorations with scents that supposedly cats hate, but he still comes back! What do you cat owners do during Christmas time to make them behave, and stay off these things that surely pose as a safety hazard?

A: Heh. Trees are big things to climb with lots of accessible steps. Not to mention all those fun toys hanging down all over the place. I don't do Christmas trees anymore. Even if you can get him to stay off with the spray bottle and such he'll still go nuts with it when he thinks no one is looking. It really is just one big toy to him. Really the only way to keep it safe is to keep him out of the room with the tree. Unfortunately cats don't understand that they are ever supposed to behave in anything other than a very cat-like manner. They do bring a lot to our lives but they aren't as trainable as dogs and children. As far as they are concerned any attempts to get them not to do something will only work as long as there is someone right there to punish them right when they are doing it. As far as they are concerned we exist to feed them, cuddle and pet them (when, of course, they want it), and to play with them. That tree, however, is all theirs to conquer and all those lights and ornaments are exciting new toys/prey to be scratched, chewed on, and tossed around. It is our cats' world and we just happen to live in it.

Q: Do you ever get angry when the Christmas Tree lights get tangled?
I was so angry I threw them earlier and now they're all broken. =(

A: if you have to buy new ones but this year put them away properly and you wont have this problem next year, take a coke bottle (empty) and wrap each strand of lights around the bottle, 1 strand per bottle I do that every year and have no trouble with tangled lights

Q: my christmas tree lights have just stopped working they are brand new .?
i changed the first painted bulb and changed the fuse is there anything else to try .

A: Make sure each bulb is secure by gently pushing it into the socket (don't remove the bulb first). If that fails, check your extension cord. Also, make sure the wall outlet is working, and that you haven't tripped a breaker. Good luck with this, and Merry Christmas. Edit: I forgot to mention checking all cords for cuts, frays, and other damage. Never use a damaged cord, it's a fire hazard. If the cord on your light set is damaged, return them to the store for a refund.

Q: How/when did the tradition of the Christmas tree and lights come about?
I know that Santa Clause(St Nick) was indeed acually St. Nicholas, and he gave gifts to the needy. SO I know that tradition

A: Honestly, I'm not totally sure; there's a lot of propaganda out there. Insofar as the tree being a part of our yearly rituals, in the modern era, I believe we can thank Queen Victoria and her Royal Consort, Prince Albert. As for electric lights, go on back to Edison. Otherwise, I think the Christmas tree may or may not have had its origins in Germanic culture. Bear in mind that the idea of nation-states didn't exist for some time (eh, we're still debating that).

Q: When were Christmas tree lights first used ?


A: 1882, two years after Edison invented and patented the light bulb. Edward Johnson wired 80 red and blue bulbs and wound them around a Christmas Tree. It didn't catch on until 1895 when President Grover Cleveland used a strand on the White House Christmas tree (of course, the time delay was also due to the fact that electricity had to be routed to American homes and cities before people could use it as well).

Q: Recycle Old Christmas Tree Lights?
Do you know if there is a place to recycle old christmas tree lights?

A: presuming they don't work, and are not worth fixing, otherwise you could free cycle them. Just recycle them as electic wiring, you can around here at least.

Q: How many christmas lights are on the christmas tree in Trafalgar Square London?


A: 500 Individual white lights

Q: Are Tesco's Christmas tree lights dim this year?
I've just put up 2 x 200 white fairy lights and they are dim, definitely not as bright as they should be? Anyone else have this problem? I'm thinking of taking them back

A: I haven't bought mine yet but if they're not bright enough that's no good, take them back!

Q: How do I make a christmas tree out of lights?
I've seen these trees in peoples yards. The tree is a 2by4 that you string lights from.

A: You must make a frame either from wood or wire , I have used a large tomato cage , you can also cut shapes out of wood as a tree or anything else that you like ,then you wire the lights on, or staple them on , and place them into the the ground using pegs to hold them down this way the wind doesn't blow them over. I hope that I was of some help to you Merry Christmas!

Q: Christmas tree lights.....not working?
I've 5 sets 3 of which work the other 2 don't...what checks can I do to get them working again.....1 set, half the lights came on

A: you could get a bulb tester and try each bulb to make sure if it was working. But really the new sets are so cheap nowadays it is hardly worth the effort. Finding the replacement bulbs are a nightmare .There are thousands of different ones. Take Care. When I was 12. I was almost electrocuted whilst trying to repair Christmas lights. I was only saved by my brother running into the room and putting the power off , I still have the scars on my hand where the live wire burnt into me... I was so close to death and was very careful of electricity after that. Ps. I later trained as an electrician and worked with electricity (safely) until retirement.

Q: How do you set up a real christmas tree and icicle lights on the outside?
Do you need to water the tree before setting it up? what are the procedures for setting it up? also how do u set up the lights outside? are there special hooks? do u need to nail them into the wall? i have a flat tar and gravel roof.

A: icicle lights hang from gutters using gutter hooks, or if you don't have gutters but shingle tiles the gutter hooks or roof hooks can slide under the first roofing tile. Not sure how to do it with hooks if you have a cermaic roofing tile roof. As for a live christmas tree, saw off about two inches (minimum) off the bottom of the trunk at an angle then set it in a 5 gallon pail of water hold it in place with dowels that you drill into the trunk that support it in the bucket by tightly fitting into the inside of the bucket (they should be spaced out evenly on tree sides of the trunk) Add an aspirin once a week to keep the water fresh and top off the water when needed.

Q: where did the tradition of putting christmas tree lights on trees originate?


A: When the German immigrants went to America they also brought along their Christmas trees. In the 1830's most Americans still considered the Christmas tree an oddity. One of the first public displays of a Christmas tree was set up by German Settlers in Pennsylvania. At the time many still considered the tree to be a symbol of pagans and it wasn't until the late 1800's that Americans began accepting the Christmas tree. Early Christmas trees were often decorated with apples, nuts, cookies, colored popcorn and candles. The invention of electricity in the early 20th century and use of electrical Christmas lights helped spread the use of the Christmas tree. It is now common in most communities through out the US to feature public displays of Christmas trees. Every year the President of the United States lights the National Christmas Tree in Washington and in New York skaters spin beneath the lighted tree of Rockefeller Center. Through Europe and the rest of the world the Christmas tree has also become readily accepted and adored

Q: I need to decorate my 100 foot tall pine tree with Christmas lights?
The tree is 100 feet tall and we dont want to get a boom lift. I thought I could make a poll out of PVC pipe, but it might be to heavy to controll. I also thought if I used a sling shot, I could sling a rock tied with rope over the top of the tree, then tie the lights on the end of the rope and pull them to the top of the tree.

A: Get one of those radio controlled helicopters to pull the rope up and then tie off your lights and pull them up. lol Try Here~ http://www.christmasdisplays.net/howtovideos.php Click the video that says"Swimming Pool Dip Net Light Stringer" --- I have a 20'-30' that I have typically used what I call the "jump rope method". If you place the lights as high as you can with a small stepladder, than walk about 20-30 feet from the tree and start swinging the rest of the lights like the bottom part of a jump rope. When I get a large enough arc, I sort of snap them up and over to the tree. It's worked well for several years and believe it or not, the lights strands have not broken. I have also had a tree service come to do some trimming a few months ago, and they used a slingshot to get their climbing ropes up to the top of my trees. This was a commercial slingshot, made specifically for the arborist trade. It consisted of a fiberglass pole about 10' long, onto the end screwed a "big" slingshot, with rubber tubing that would stretch about 6' or so and a little sack in the rubber tubing to hold the "thrown weight" which was attached to a pull cord. It was quite accurate, and went up to the tops of my trees. He said they ran around $100.00.
