Does this use electricity?....?

Question

If an electrical; appliance is switched off (not even on standby) but is still switched on at the wall socket... does this use electricity???

Answer 1

no, there may be a small electrical current still in the wire but wouldn't use any more from when it was switched off to back on again

Answer 2

Depends on the device.

Many devices use electricity even when switched off. You see the power switch in many devices is not really a true on/off switch. Devices use a small light duty switch, to turn a circuit on and off. In order for the device to sense if you are pushing the power switch, there is power applied to the switch all the time. Since these circuits are not 100% efficient, there is a small amount of energy used.

Many older devices, like cable TV boxes, used just as much electricity whether they were on or off.

On another note, technically EVERY electrical devices uses some power. You see, every material has some resistance, even air and plastic. So even your electrical outlet just sitting there is using a miniscule amount of power, as are the wires feeding it.

Answer 3

It can, it depends on how it is wired. Many appliances contain transformers, which have a primary coil connected to the mains and secondary coils used to supply current, often at a different voltage to other circuits. If the switch is in the secondary circuit there may still be current running through the primary coil of the transformer.

Answer 4

Generally no, unless it has a power transformer (like a black box or the plug on ur moblile charger) then it would use a bit.

Answer 5

No but you could rick damage if you have a lightening strike as it will surge the line.

Answer 6

No.

Answer 7

No............
