What is the power source in this circuit?

• Bulb

• Switch

• Wire

• Battery

The voltage stays the same in a series circuit.

• True

• False

What is a parallel circuit?

• It is a circuit that has one path for energy to flow.

• It is a circuit that has no paths for energy to flow.

• It is a circuit that has several paths for energy to flow.

• None of the above.

Circuit "A" is broken, because:

• the switch is open

• the switch is closed

• the switch is black

• the switch is not there

What type of circuit is shown in the picture?

• Series Circuit

• Broken Circuit

• Parallel Circuit

• Open Circuit

This steel paperclip would allow electricity to flow through it because:

• it is a conductor

• it is an insulator

• it is friendly

• it breaks the circuit

An incomplete circuit is shown.
To complete the circuit, a wire should be placed from —

• Point D to Point C
• Point B to Point C
• Point A to Point D
• Point B to Point D

Does this diagram represent a series or parallel circuit?

• series circuit
• parallel circuit

When voltage is increased and resistance is constant, current...

• increases 
• decreases 
• is constant 
• cannot be determined
