Circuits

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.

The total resistance in this circuit is 

• 100 ohms
• 450 ohms
• 400 ohms
• 30 ohms
