Back

switch

Front

A substance, usually a metal like copper or aluminum, that allows electricity to flow is a ____________________.

Back

conductor

Front

What is the purpose of a battery in a circuit?

Back

To provide the electrical energy needed to power the circuit.

Front

What is an open circuit?

Back

A circuit that is not complete, preventing electricity from flowing.

Front

What is a series circuit?

Back

A circuit where components are connected in a single path, so the same current flows through all of them.

Front

What is a parallel circuit?

Back

A circuit where components are connected across common points or junctions, allowing multiple paths for current.

Front

What happens when a switch is closed?

Back

The circuit is complete, allowing electricity to flow.
