Multiple Choice

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

Multiple Choice

In a Parallel circuit the current is

• the same at every point

• split between the branches

Multiple Choice

In a Series Circuit the Current...

Multiple Choice

Which best describes a simple series circuit?

• Electricity flows along one pathway.
• The flow of electricity comes from the switch.
• Electricity flows along many pathways.
• The flow of electricity comes from the light bulb.

Multiple Choice

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.
• The other bulbs will stay on
• The other bulbs will get dimmer.
