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

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

• Circuit X is brighter than circuit Y
• Circuit Y is brighter than circuit X
• Both circuits have the same brightness
• Neither circuit will light the bulbs

The bulb....

• lights up brightly
• does not light due to a short circuit
• does not light as the cells push against each other
• may blow as it is in two circuits

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