Series or Parallel

Provides only one path for the electrons to follow.

• Series

• Parallel

The same current flows through each part of the circuit

• Series

• Parallel

The different parts of the circuit are on separate branches.

• Series

• Parallel

An electrical circuit that provides a pathway for electrons to flow

• Series

• Parallel

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current is divided between the three light bulbs.

Does this diagram represent a series or parallel circuit?

• series circuit

• parallel circuit

If bulb 1 burns out, what will occur?

• bulbs 2 and 3 will go out

• bulbs 2 and 3 receive more volts

• bulbs 2 and 3 will stay lit

• nothing will happen

A break (like a burned out light bulb) in the circuit does not stop the flow to the remaining devices.

• Series

• Parallel

The total resistance of a series circuit is equal to the sum of individual resistances.
