What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to a device and back.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical path that allows current to flow and power devices.

Front

What is an open circuit?

Back

An open circuit is a broken electrical path that prevents current from flowing.

Front

What happens to electrical energy in a heater?

Back

It is transformed into thermal energy.

Front

What happens to electrical energy in a light bulb?

Back

It is transformed into thermal and light energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the energy of moving particles.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit, turning it on (closed circuit) or off (open circuit).

Front

What is a power source?

Back

A power source is a device that provides electrical energy, such as a battery or power outlet.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, like copper or aluminum.
