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.
No, a lamp will not work if you disconnect it from the wall outlet. The outlet provides the electrical power necessary for the lamp to function, so without that connection, the lamp has no source of electricity. Even if the lamp is plugged in but turned off, it still requires a connection to the outlet to operate.
The lamp has electrical energy, which is converted to light energy when the lamp is turned on.
The amount of electricity a plugged-in lamp uses depends on its wattage. A typical 60-watt bulb, if left on for one hour, uses 0.06 kilowatt-hours of electricity.
Yes, a lamp can have potential energy if it is raised to a certain height above the ground. The potential energy is stored in the lamp due to its position relative to the ground, and it can be converted into other forms of energy, such as light and heat, when the lamp is turned on.
A bulb in a lamp converts electric energy into light and heat energy.
no because when you remove the lamp the circuit is still open; even if the switch is on
it starts with electrical thats the main one but there is more
The energy transfer for a lamp plugged into the wall involves the electrical energy from the power source (wall outlet) being converted into light energy by the lamp's bulb. The electrical energy powers the lamp's circuit, which then produces light as a form of energy.
the form of energy changes and the total of energy increases
Yes. Not as much but if it is plugged in it will still use some power.

Energy input minus useful energy output. So if you were using a lamp you could work out how much energy was going in and how much was actually coming out in light. Then whatever's leftover is being wasted.

There's millions of ways! Did you know that if you turn off a lamp that is plugged into the wall but do not unplug it, you're still wasting energy? When you leave a room for a long period of time, unplug some of your electronics! I know that isn't really saving energy in your COMMUNITY, but....You can make a garden in your community and get fresh fruit and vegitables instead of eating imported food.You could turn off lights when you leave a room, carpool with friends, buy solar panels, ride your bike, of course recycle, you can take shorter showers, when your done put your computer on sleep mode.

when you turn on a lamp it is first light energy to chemical energy!
