If the voltage on V1 = 5V and voltage on V3 = 2V, what would be the voltage on V2?

• 1V
• 6V
• 3V
• 4V

In a series circuit the current is the same at all points?

• True

In a parallel circuit the current is the same at all points.

• True
• False

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.

When you remove a bulb from a three bulb circuit, and the other two bulbs go off, then the bulbs must have been connected in __________.

• parallel
• series
• open
• closed

The total resistance of a parallel circuit is always...

• greater than the sum of all the individual resistances.
• greater than any of the individual resistances.
• equalto the smallest of the individual resistances.
• less than any of the individual resistances.
