Accepted Answer

A complete path called an electric circuit.

Answer

A metal surface for the current to flow on.

Answer

An open path without any connections.

Question 18

In a circuit, current flows through both the wire and the bulb.

Accepted Answer

True

Answer

False

Question 19

What happens to the wire in the circuit?

Accepted Answer

It provides a path for the current but does not glow.

Answer

It glows.

Answer

It sparks.

Question 20
