What happens in a closed circuit?

• The circuit is open and no current flows.

• Electric current can flow continuously.

• The circuit is short-circuited and current stops flowing.

• Electric current cannot flow.

What is a parallel circuit?

• An electrical circuit that has only one path for the current to flow.

• An electrical circuit that has multiple sources of current.

• An electrical circuit that has no path for the current to flow.

• An electrical circuit that has multiple paths for the current to flow.

What is a series circuit?

• An electrical circuit in which the components are arranged in multiple paths

• An electrical circuit in which the components are arranged one after the other in a single path.

• An electrical circuit in which the components are arranged randomly
