Vocab Review (Electricity)

The property of a material that allows charge to flow is...

• Potential difference (voltage)

• Conductivity

• Resistance

This potential energy is due to the difference in concentration between electrons within a power source (like a battery):

• Potential difference

• Current

• Resistance

An electric current requires which of the following to flow?

• A closed path

• A switch

• An insulator

A current that is able to move in both directions is called:

• Alternating current (AC)

• Direct current (DC)

• Voltage current (VC)

Batteries allow which type of current to flow through them?

• Alternating Current (AC)

• Direct current (DC)

• Voltage current (VC)

All of the following would make a GOOD conductor of electricity except which of the following

• A silver key

• A copper wire

• A glass window

Insulators, like plastic or rubber, are NOT good conductors of electricity because

• They allow charge to flow about half of the time.

• They allow charge to flow

• They allow very little charge to flow

A thin wire will provide MORE RESISTANCE than a thick wire.

• True

• False

A short wire will provide MORE RESISTANCE than a long wire

• True

• False

A cold wire will provide MORE RESISTANCE

• True

• False
