the form of energy changes and the total of energy increases
Nothing YET- but when the toaster is turned on, electrical energy is changed to heat (and a little light)
it is not recommended to use your cell phone when charging, this could cause the circuits to short. Ideally you should charge your battery when your phone is turned off
Bulbs are things that are plugged into light sockets, and they light up when the electricity is turned on.
If your laptop is turned on and it looks like it's plugged in, the batter could possibly be dead or the connection from the outlet to the computer has a problem.
You cooked it
Hot hair in blowen out which tends to absorb the moisture from your hair .
If the outlet is powered with the key off, then yes it will slowly drain the battery.
That the outlet only has power when the ignition is turned on.That the outlet only has power when the ignition is turned on.
a microwave or a x-ray. Because when the microwave for example is plugged in or turned on is electrical energy and when the food is being cooked is when electromagnetic energy is used. Hope I Could Help :]
The formula you are looking for is I = W/E. W = kW x 1000.
