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.

What is an electrical circuit?

• lets you turn the energy on and off
• a closed path where where electricity flows
• stop electricity from flowing through

An incomplete circuit is shown.
To complete the circuit, a wire should be placed from —

• Point D to Point C
