What flows in a circuit?

• Positive and negative charges

• Negative ions

• Electrons

• Protons

In order for current to flow you must have

• A switch that is open

• A complete path for current

• Two light bulbs in parallel

• Two light bulbs in series

• All of the above

When one light bulb in a parallel circuit burns out the other light bulbs burn

• Do not burn at all

• Burn brighter

• Burn the same as before

A single bulb burns out in a circuit, which causes all the bulbs to stop burning. This is an example of

• A series circuit

• Parallel circuit

• A compound circuit

• A racing circuit

As bulbs are added in series, what happens to the current flowing through the bulbs?

• Current increases

• Current decreases

• Current remains the same

As bulbs are added in parallel, what happens to the current leaving the battery?

• Current increases

• Current decreases

• Current remains the same
