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 has more than one path to flow through

Simple, Series, or Parallel?

• Simple

• Series Circuit

• Parallel Circuit
