Does a burned out lightbulb still use electricity if switch left on?
Question:If I have a lamp and all of the bulbs are burned out but the switch was left in the on position, is it still using elecctricity ? If it is a multi-bulb lamp, does it use less electric if you remove one of the bulbs? How about if all of the bulb sockets have bulbs but a few are burned out? I have an 8 bulb chandelier with a few bulbs burned out. Someone told me that if I turn it on, it uses the same amount of electricity with the burned out bulbs left in as it would if all of the bulbs were working, but would use less if I at least removed the dead bulbs.
Answers:
No it would not pull the same.With the bulb being out that bulb is pulling no current.The electricity would still be in the socket though.The best way to explain it is like a waterhose if it is turned on there is water there but until you turn on the faucet on the end no water is being used.
Yes a burned out lightbulb still uses electricity. If you want to test this you can take the lightbulb out and stick your finger in the socket (though obviously i do NOT approve doing that lol) When the power to say a lamp is on, it goes to the socket, wether anything uses it or not, dont matter.
Though i dont know it all, im not sure if it uses less electricity not having a working bulb, or like you said a multi-bulb and 1 or 2 out... Though i would imagine it would use the same ammount of electricity either way.
Hope this helps
No, the circuit is not complete, so there is no electricity flowing. If you stick your finger in a light socket, then your finger is completing the circuit which is why you will get knocked onto your behind. And you'd deserve it too. Electricity has to make a loop in order to work. It has to go out from the source to wherever it is working and then come back in order for anything to happen. If the filament in the bulb is burned out, then the loop (circuit) is broken and electricity cannot flow.
Yes. Anything plugged into an outlet draws electricity and will add to your bill. Always unplug any appliance untill you want to use it. This includes toasters, crockpots, lamps, coffee pots, etc. Even when not in use, anything plugged into an outlet will draw a small amount of electricity, so you are causing your bill to be higher. If you have more than 1 TV, always unplug it unless you intend to watch it.
Does a dead man eat? No and a dead bulb does not consume electricity. Surely a multi bulb lamp uses less energy with the fewer bulbs lit.
Ok, Basic electricity :
With out a completed circuit, the appliance will not use electricity.
Each bulb consumes or uses amps when it is actuated, so naturally burnt out bulbs will not use any, so the fixture will use less electricity.
T.V.'s today are almost all remote controlled, so they are in standby mode. This means that they are partially on and just waiting to actuate the screen when you hit the on button. So these will use almost as much juice in hibernate as when active.
Most kitchen appliances, toaster, mixers, crock pots, do not use anything until turned on. I f they have a clock or a light that stays on, then they are drawing power all the time.
Just to clarify, a 60 watt bulb cost about .08 cents and hour to run, so 8 of them would be..64 cents per hour, and if a train left Kansas traveling at 60 MPH. simple math stuff.
If you are concerned about power consumption, change to the CFC bulbs. Besides costing less to operate, they do not generate near the heat of regular incandescents, so make it cheaper to keep your house cool in the summer.
A typical chandelier will consume less power as each bulb burns out. When a bulb burns out it opens the path in the bulb. Think of it this way. If you have a road system where you can take one of 8 different roads to get to your destination you can pass a lot of cars on that systems. As each road closes the amount of cars that can flow to the destination drops. When the last road is closed no one can get to the destination. If you don't believe this think of it this way. Put all 8 bulbs in and notice the amount of light. The amount of light is an indicator to the amount of power being consumed. With 7 lights removed you will have very little light and very little power consumed.
Burned out lightbulbs don't use electricity at all. Lightbulbs work by converting electricity to heat and light when it passes through the tiny wire in the bulb. When it burns out and the tiny wire breaks, no electricity can flow through it and therefore it uses no energy. Electricity can't be used up like that, because it would have to be transformed into another type of energy, and since here there is no heat, light, movement, or anything else produced, the instant the bulb burns out less electricity is used up.
