Review - Test 2

A parallel circuit

• has only one path for current to travel

• has more than one path for current to travel

• does not allow electricity to travel through it

• has magnets that cause electric current

In a parallel circuit, if one connection is broken, all of the connections stop working.

• True
• False

What 'flows' in a wire?

• Protons
• Neutrons
• Atoms
• Electrons

This is an example of a ______ circuit

• Series
• Parallel
• Open
• Dihexihedral

Pick the correct sentence.

• This circuit will work because it is a closed circuit.
• Energy will freely flow in this circuit.
• This circuit will not work because there is no energy source.
• This circuit will not work because there is no switch.

This is an example of a _______ circuit

• open

• series

• parallel

• switch

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.

What is the energy source for a circuit?

• Light bulb
• Battery
• Wire
• Switch
