How does a circuit turn a switch on and off?
A switch makes a physical break in the electric circuit. With the circuit broken the electricity can not flow. When the switch is turned the other way the circuit is completed and the current/electricity can flow.
Lowering Your Average Electricity Bill Per Month?
One of the best ways to lower your average electricity bill per month is to run all of your electronics through power strips that you can turn off at night. If the electronics are still plugged into the wall on their own, they will be using electricity all night long -- even if you have turned them off. Power strips have an on/off button that can cut off the charge, and they are not susceptible to this same problem. If a power strip is turned off, there is no current. Doing this can cut your electricity bill by a fifth.
If a lamp is off but still plugged in is it wasting energy?
No electricity can be used or wasted if the lamp itself is turned off. It makes no difference if it has been turned off at the wall outlet or at the lamp itself. It is the same situation as a flashlamp that has a light bulb supplied by a battery. If the flashlamp is switched off the battery inside it is still there, waiting to feed the light bulb with current, but the current can only flow into the light bulb when the switch on the flashlamp is turned on.
What happens with the energy associated to the magnetic field of a coil with electric current if the electric current is turned off?
The magnetic field or energy associated with the magnetic field will no longer be generated if the current is turned off.
How are electro magnets different from other magnets?
An electromagnet can be turned on and off, with an electric current and a magnet can not turn off
How much electricity does a lamp used when turned off?
When the switch is open there should be no current flow.
Does a lamp use electricity when it is turned off?
A standard lamp will not use any electricity when it is off.
Does a lamp use electricity when turned off?
No, it should not use any electricity when off. If it is, you have a short or a ground.

What doesn't electricity flow?
Through an insulator. When it is turned off.
Will you get in trouble if your electricity got turned off and you turned it back on?
yes, this is considered theft of service.
How is the rotation of a windmill turned into an electric current?
the windmill goes fast to make electricity
What are electromagents?
Magnets that are turned on by passing an electric current through them, and turned off by not allowing an electric current through them.
When a lamp is switched off is the electrical current to the light open or closed?
Open and closed does not refer to electrical current or the flow of electricity. Open or closed refers to the state of an electrical circuit. When a lamp is turned on electricity flows through wires, the switch and the lamp; and the circuit is considered closed. When a lamp is switched off the circuit is considered open (or broken) and the flow of electric current is stopped.

How does an electrical bill work?
You get the bill. If you pay it, the electricity stays on; if you don't pay it, the electricity gets turned off.
