In order for lights to light up on a series circuit, the switch needs to be open. True False

## Step 1<br />In a series circuit, the current flows through each component in the circuit. This means that the current flows through the switch, the light bulb, and any other components in the circuit.<br />## Step 2<br />If the switch is open, it means that the circuit is broken. This is because the switch is acting as a break in the circuit, preventing the current from flowing.<br />## Step 3<br />Since the circuit is broken, the light bulb will not light up. This is because the current cannot flow through the circuit to the light bulb.<br />## Step 4<br />Therefore, for the lights to light up on a series circuit, the switch needs to be closed, not open.
