1

What do volts measure?

The difference of potential between two points.

2

What do amperes (amps) measure?

The number of electrons that move past a specific point in one second.

3

What do ohms measure?

Resistance, including anything that could limit the flow of electrons.

4

What is a current?

Something that occurs when electrons move from one place to another.

5

What is the purpose of a conductor?

It allows electrons to move freely.

6

What does an insulator do?

Discourage electric currents.

7

What does a watt measure?

Power, the rate at which electrical energy is consumed or formed into another type of energy.

8

What is a watt-hour?

The amount of energy used in one hour at a rate of one watt.

9

What is a kilowatt-hour?

Most electricity is measured in this. It's how much energy you would use of you ran a 1000 watt (1kilowatt) device for an hour

10

How do you find watt-hours?

Multiply wattage by time (hours)

What is a circuit?

The path of an electrical current
