Electric Circuits

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning electricity cannot flow through it.

Front

What is a conductor?

Back

A conductor is a material that allows electrons to move easily, enabling the flow of electricity.

Front

What is an insulator?

Back

An insulator is a material that does not allow electrons to move easily, preventing the flow of electricity.

Front

What is resistance in an electrical circuit?

Back

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

Front

What materials are commonly used to make electrical circuits?

Back

Most electrical circuits are made of metal, which is a good conductor of electricity.

Front

What happens when you add more batteries to a circuit with one light bulb?

Back

The light bulb will get brighter because more batteries provide more voltage.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows electricity to flow through it.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for electricity to flow.

Front

What is the role 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, driving the flow of current.
