What are the things that hold light bulbs on ceilings called?
Chandelier holds many bulbs. If it is just one bulb in a fixture fastened directly to the ceiling it is a ceiling light fixture.
I can't turn my ceiling light off HELP!!?!?! :( the light pull cord wont pull anymore.?
As long as the bulbs are out, there's no electricity flowing through them, so you're not running up your electric bill. It's actually a really practical solution to a temporary problem. Need lights? Screw them in a bit. Turn 'em off? Lefty-loosey. If you're not comfortable working on things like residential wiring, which is kind of what I'm sensing, call the landlord and have him/her come out and repair it. The part needing replaced is a few bucks at most and readily available at any hardware store. Should take about 10-15 minutes tops. But until then, unscrewing the bulbs will do you just fine, you're not running up any additional costs. Hope this helps!
How do I shut off a ceiling fan when the string that I pull to turn it on has fallen out?
How do I shut off a ceiling fan when the string that I pull to turn it on has fallen out- I went to turn on the fan and the metal "beaded" string thing that I turn the celing fan on with completely ripped out! I screwed off the the area where the string came out of and under that was a plastic "knob thing" that the string came out of so I tried to wear down the knob thing and twist it off with pliers, scissors to see if inside it there was a piece of the string that i could pull to turn the fan off, but all that did was damage the knob thing-I couldn't get it off! Also,under the fan, there's a light bulb area-I took out the bulb, and took out the thing that the bulb "screwed" onto and inside that little compartment were like 3 wires running into a small white rectangular compartment that was screwed shut-I thought about cutting a wire but I'm afarid to get electrocuted! I figured out how to keep the fan from running by switching a little black switch that's on the side of the body of the fan-but the fan is still on-the fan blades aren't spinning anymore but I can hear that buzzing sound that means its on. What do I do! How do I shut the fan off MYSELF-I can't call anybody to fix it!
My ceiling light turned on by itself.?
I think it was just his way of saying Happy anniversary. You might try to justify how it turned on but if it had a pull chain and nobody pulled it , well that kind of narrows down just how it got lit up doesn't it? Several friends of mine have had ghostly encounters and my Wife and I have even seen our share and had experiences so don't be afraid and just acknowledge them from time to time to let them know they are not forgotten and are still loved and missed very much.
If a lightbulb is burnt out does it still consume electricity when you turn the light switch on?
I agree with Marcos in the case of old incandescent lights, however, its worth noting that if you are using fluorescent tubes in a multi lamp fitting i.e. commercial environment the control gear consumes (approx. 12%) electricity independent of the tubes. So you could still consume when a lamp has gone.
Why do my light bulbs keep blowing out?
I assume we're talking incandescent bulbs here. The classic bulb is a tungsten filament in a glass vacuum envelope.The wear out mechanism for these is that the Tungsten vaporizes a little bit at a time and deposits on the glass. Contaminents such as molecules of air (oxygen) in the vacuum envelope probably accelerate this a little. Ultimately the tungsten filament becomes too thin and it physically breaks and that is the end of life of the bulb. Now many people say that the inrush current causes a thermo-mechanical shock which breaks the filament and that is the cause of failure. That is correct only to the extent that the filament has been weakened by a thousand hours of vaporization. The cause of the break was the loss of tungsten and the shock was the straw that broke the camel's back. A healthy, properly designed bulb will not break from the thermal shock without the long term weakening. It just seems that way because very often the bulb will break when power is applied. Also if the vacuum envelope develops a leak (due to physical failure) then it will fill with air and when you turn on the bulb, the oxygen causes the tungsten to literally burn and fail immediately. Again a lot of people attribute this to inrush current.Yes the filament runs at thousands of degrees and the initial current surge is high. The resistance is very temperature sensitive and goes to a higher resistance state which drops the current significantly (but its still nearly an amp for a 100W bulb). The filament is designed to physically withstand large inrush currents. It won't fail with repeated actuations if the tungsten filament is fully intact. Those who claim its the inrush current that causes bulbs to burn out only get 10% credit for their answer, BEACUSE IT'S NOT THE ROOT CAUSE! Ultimately incandescent light bulbs can be made more stout but there's a multi-way tradeoff between filament thickness, long life and power consumption and brightness. And they've already been marked for retirement because of their low efficiency.
When there is no light bulb in the the socket but the light switch is on, is electricity being used?
For current to flow in a circuit the circuit must be closed. If there is no light bulb in the socket the current cannot flow across this gap in the circuit, therefore no electricity is being used.If the circuit is designed such that the light socket is in parallel to the power supply then there may be another node for the electricity to flow through, however as there is no "load" then you have a short circuit. This means that the electricity flows from the source, around the wires, and back to the source. This isn't good! You may end up with melted wires or the power source blowing up. When there is no resistance to the flow of charge carriers you get a very high current, a large amount of energy is transferred in a very short amount of time. This large amount of energy needs to go somewhere, either back to the source or transformed in the wires as heat energy. In your home you will find a circuit breaker. This provides protection in the event of high current flow, and will break the circuit and stop the flow of current.Alternatively you may find if you are using a lamp with a plug, the plug may be fused (depending on the country you live in), this fuse in the plug has a small piece of wire inside that is rated for a certain amount of current. If there is a short circuit and the current goes above the rated limit, then the wire inside the fuse melts - stopping the flow of current.
How do I wire a ceiling fan to a light switch?
Like thisFour notes about this installation.This is for if your power is at your fixture.If you have only 2 wire romex that's ok. Just hook up the white wire from the switch like the red shown here. (Code requires that you remark the white, on both ends, as something other than Green, Gray or White. I suggest Red or Black)The colors for the fan wire and the light wire on this diagram may not be the same as your fixture. Know the difference.In this configuration you must have the switch on to use either the light or the fan. I recommend moving the 'fan' wire on thr fixture from the red wire to the black wire. This will make the fan 'always on', and you control it from the pull chain, and the switch controls the light.
The electricity in my room turns off when I flip my light switch off. How can I fix this?
Call an electrician. Do NOT try and fix this yourself.Is there really only one wall outlet in the room? Or is only one outlet turning off with the light switch? Sometimes no ceiling light is installed, and instead a wall outlet near the door will be wired to a switch on the wall so you can plug a table lamp in. There are usually other outlets in the room.But you don't give any details, or say where you live.
