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 kind of circuit is this?

• series
• parallel

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit
• series circuit
• parallel circuit
• open circuit

• A₂ = A₃
• A₂ + A₃ = A₁
• A₁ + A₂ = A₃
• A₄ = A₂ - A₃

This circuit does not work because…

• the bulbs are not connected properly
• the single cell is not powerful enough
• there is a break in the circuit
• there is a short crcuit
