Which point will have the most current flowing through it when the switch is closed?

• Point A

• Point B

• Point C

• They all have the same amount of current

Which resistor will cause a greater voltage drop when the switch is closed?

• The 10Ω resistor

• The 15Ω resistor

• They are the same

• There is no way to know from the diagram

In a series circuit, a 20 Ω resistor will cause twice the voltage drop that a 40 Ω resistor will cause.

• True

• False

If there is a break in a series circuit with light bulbs, what will happen?

• No current will flow and no light will be produced.

• Current will flow from the positive end of the battery and all bulbs before the break will light up.

• Current will flow from the negative end of the battery and all bulbs before the break will light up.

More resistors in a series circuit will use up more current.

• True

• False

The total voltage drop of all the resistors in a series circuit is equal to the voltage of the battery or source.

• True

• False
