Series and Parallel Circuits

• Series circuit - Bulbs are lit
• Series circuit - Bulbs are off
• Parallel circuit - Bulbs are lit
• Parallel circuit - Bulbs are off

This circuit does not work because…

• the bulbs are not connected properly
• two cells are not powerful enough
• there is a break in the circuit
• the cells are facing each other

• all bulbs are lit equally
• the two top bulbs are brighter
• the single lower bulb is brighter
• the single bulb does not light and the other two are dim

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

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
