If current is not used up when you switch a light on what are you actually paying for when you pay your electricity bills?

Current is not actually "used up" like firewood; rather, it is used like water powering a paddle-wheel on a water mill. The electrons that make up electricity have to be pushed out of the power plant and brought back in again by steam-powered generators which burn coal or use nuclear energy to heat water to drive the turbines.

When you pay your electricity bill, you are paying for the energy consumed by the light and other electrical devices. The energy is measured in kilowatt-hours (kWh), which represents the amount of power consumed over a period of time. The bill includes costs for generating and distributing the electricity, maintenance of the power grid, administrative expenses, and any applicable taxes or fees.

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.
Will a circuit work without a switch?
Yes a circuit will work without a switch but the only problem will be is that electricity will be wasted and there will be no device to stop the flow of current
An object that stops the flow of electricity is called?
An object that will stop the flow of a current is called a switch.
What protects equipment from too much current by tripping a switch that breaks the circuit and stops the flow of electricity?
Circuit Breaker
What device used to stop and start the flow of electricity in a circuit is a?
A switch is a device that stops and starts current flow in a circuit.
What can current electricity be controlled by?
a switch
What is the switch and the bulb in electricity?
A switch is used of stop the current flow in a circuit and the bulb can be classed as the load in a circuit.

What can a relay be used?
A relay is an electrical switch. It allows a low current "switch" circuit to control the electricity flow of a high-current circuit load
Will a circuit work without a switch?
Yes a circuit will work without a switch but the only problem will be is that electricity will be wasted and there will be no device to stop the flow of current
What starts a car?
The ignition switch completes the circuit of electricity from the battery to the starter that actually turn the engine over and starts it.The ignition switch completes the circuit of electricity from the battery to the starter that actually turn the engine over and starts it.
How much electricity does a lamp used when turned off?
When the switch is open there should be no current flow.
An object that stops the flow of electricity is called?
An object that will stop the flow of a current is called a switch.
Does lamp in off position use electricity?
No. When the switch is open, off position, no current flows. The light needs current to operate.
What is in a light bulb when it's switch is turned on or connected the electricity flows through what we call?
A closed current
Is an open switch in an electrical circuit to prevent current flow?
Yes, an open switch breaks the circuit and prevents electricity flowing through. A closed switch on the other hand completes the circuit and in turn helps electricity travel through the circuit.
If you have a light and one switch that controls it what are the light and the switch wired in?
A light controlled by a switch are necessarily wired in "series", meaning that the electricity must pass through all components if the circuit is to operate correctly, assuming you actually have a source of electricity wired in as well.
