Electricity & Magnetism

Front

What is a conductor?

Back

A material that allows electricity to flow through it, such as metals like copper and aluminum.

Front

What is an insulator?

Back

A material that does not allow electricity to flow through it easily, such as rubber or glass.

Front

What is Ohm's Law?

Back

The principle stating that the current in a circuit equals the voltage difference divided by the resistance (I = V/R).

Front

What is static electricity?

Back

The buildup of electric charges on the surface of an object.

Front

What is a turbine?

Back

A large wheel that rotates when pushed by steam, wind, or water, providing mechanical energy to a generator.

Front

What is resistance in an electrical context?

Back

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

Front

What is the unit of electric current?

Back

Ampere (A).

Front

What is voltage?

Back

The electric potential difference between two points, measured in volts (V).

Front

What is a circuit?

Back

A closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is an electromagnet?

Back

A type of magnet in which the magnetic field is produced by an electric current.
