A circuit with "two or more pathways" for electric current is called a.....

• Parallel Circuit

• Series Circuit

• Open Circuit

• Circuit City

The unit of measurement for resistance is:

• Ampere (A)
• Volt (V)
• Ohm (Ω)

The "pressure" or "push" that moves electrons through a circuit is called:

• Resistance

• Voltage

• Electrical load

• Current

Adding another branch to a parallel circuit ______________ the total current in the circuit.

• Increases
• Decreases
• Does not change

True or False: If one device fails in a parallel circuit, the other devices function normally.

• True
• False

Adding another load (such as a light bulb) in a series circuit ______________ the total current in the circuit.

• Increases
• Decreases
• Does not change

What is a conductor?

• a material that allows electrons to flow easily

• a material that does not allow electrons to flow easily

• a person in charge of an orchestra

What is an insulator?

• a material that allows electrons to flow easily

• a material that does not allow electrons to flow easily

• a material that keeps you warm

If the bulb on the right burned out, what would happen to the bulb on the left?

• it would stay lit

• it would not light up

• it would glow brighter

• it would glow dimmer
