What is a parallel circuit?

Back

A parallel circuit has multiple paths for electrons to flow.

Front

What is a series circuit?

Back

A series circuit has only one path for the electrons to flow.

Front

What do a blender, ceiling fan, and toy car have in common?

Back

They all contain an electric motor.

Front

What happens to current as resistance increases in a circuit?

Back

As resistance increases, the current will decrease.

What is the function of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit.

Front

What is an electric motor?

Back

An electric motor is a device that converts electrical energy into mechanical energy.

Front

What is resistance in a circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.
