Front

What is resistance?

Back

the material's tendency to resist flow of electrons

Front

What is a parallel circuit?

Back

A circuit where components are connected across common points, providing multiple paths for current.

Front

What is the device that uses electromagnetism to convert electrical energy into mechanical energy?

Back

electric motor

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electricity to flow through it easily and an insulator does not.

Front

What is an electromagnet?

Back

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

Front

What is Ohm's Law?

Back

The relationship between voltage, current, and resistance, expressed as V = IR.

Front

What is a series circuit?

Back

A circuit where components are connected end-to-end, so the current flows through each component in turn.

Front

What is static electricity?

Back

The buildup of electric charge on the surface of objects.

Front

What is a volt?

Back

The unit of electric potential difference, representing the amount of work needed to move a charge between two points.
