Circuits

The job of a battery in a circuit is to...

• move the charges
• charge the charges
• make the charges
• electrify the charges

What do resistors do to charges?

• Stop the flow of charge
• slow the flow of charge
• speed up the flow of charge
• reverse the flow of charge

The battery determines the direction of charge flow in a circuit.

• True
• False

Do resistors use up the charges?

• Yes
• No

If light bulbs always have charge in them, why aren't the bulbs always lit?

• the charges must be positive
• there must be unequal numbers of + and -
• the charges aren't strong enough
• the charges must be moving

What kind of charge is required to light up a light bulb?

• positive
• negative
• neutral
• moving
