What happens in an open circuit?

Back

In an open circuit, the electrical path is broken, and electricity cannot flow, so devices like bulbs will not light up.

Front

What happens in a closed circuit?

Back

In a closed circuit, the electrical path is complete, allowing electricity to flow and devices like bulbs to light up.
