Flashcards

1

No charge

Neutron

2All magnets

have a north and

south pole that creates this

Magnetism

3

can be compared to

the gravitational force

of electricity...

Electrical potential energy

4

an apparatus for changing a given

electrical current into another current of different voltage

Transformer

5

is a device that measures the

potential difference two points in an electric circuit

VOLTMETER

6

is the unit used to measure

electrical current

Ampere

exist whenever electric charges

are moving

Magnetic Fields

10

is a device that converts

mechanical energy into electrical energy

GENERATOR

11

refers to the change in

electrical potential in a circuit

Potential Difference

12

is a measure of the electrical

energy available

Voltage

13

electricity moving through a circuit

Current

14

The way by which the ability to flow through a circuit is slowed down

Resistor
