Front

What is a generator?

Back

A device that converts mechanical energy into electrical energy using electromagnetic induction.

Front

What is an insulator?

Back

A material that does not allow electrons to move easily, preventing the flow of electricity.

Front

What is electric current?

Back

The flow of electric charge, typically measured in amperes.

Front

What is an electromagnet?

Back

A type of magnet that can be turned on and off using electricity.

Front

Is a magnetic field visible to the eye?

Back

False, a magnetic field cannot be seen.

Front

What is a conductor?

Back

A material that allows electrons to move freely, enabling the flow of electricity.

Front

What is the principle of electromagnetic induction?

Back

The process of generating electric current by changing the magnetic field around a conductor.

Front

What is a motor?

Back

A device that converts electrical energy into mechanical energy.

Front

What is resistance in an electrical context?

Back

The opposition to the flow of electric current, measured in ohms.

Front

What is a transformer?

Back

A device that changes the voltage of alternating current (AC) in a circuit.
