Electricity and Magnetism Review

Front

What is a circuit?

Back

A closed path that electric current follows.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, there is only one path for current to flow, while in a parallel circuit, there are multiple paths.

Front

What happens in a series circuit if one bulb goes out?

Back

The entire circuit is broken, and all bulbs go out.

Front

What happens in a parallel circuit if one bulb goes out?

Back

The other bulbs remain lit because there are multiple paths for current to flow.

Front

Where is the magnetic force strongest on a bar magnet?

Back

At both the north and south poles of the magnet.

Front

What is a magnetic force?

Back

The force a magnet exerts on another magnet, on iron or similar metals, or on moving charges.

Front

What is voltage?

Back

The electric potential difference between two points in a circuit.

Front

What is current?

Back

The flow of electric charge in a circuit.

Front

What is resistance?

Back

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

Front

What is an electromagnet?

Back

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