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.

If the voltage across a circuit of constant resistance is doubled, the power dissipated by that circuit will

• be four times as large.

• be two times as large.

• decrease to one-half the original power.

• decrease to one-fourth the original power.

• 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
