1

Unit of charge.

Coulomb

2

An atom or molecule in which the charges are aligned so that one side is slightly positive and the other is slightly negative.

Electrically Polarized

3

The flow of electrons.

Electric current

4

Measures the rate of electrical flow.

Ampere

5

The potential energy compares with the quantity of charge.

Voltage

6

The ability of a material to resist the flow of charged particles.

Electrical Resistance

7

Describes the relationship between voltage, current, and resistance.

Ohm's Law

8

One prong is live, the other prong is neutral. The large, round prong is the ground.

Electric plug

9

Energy flows in one direction

Direct Current

10

Energy flow reversing direction in the circuit.

Alternating Current

11

Any path in which electrons can flow.

Circuit

12

Electrical circuit in which devices are connected so that the same current exists in all of them.

Series Circuit

13

Electrical circuit in which the devices are connected so that the same voltage acts across each one and completes the circuit independently of the others.

Parallel Circuit

14

Circuits that carry more than a safe amount of current.

Overloaded

15

Act as switches. They break the circuit to prevent overloading.

Fuses and circuit breaker

16

The force between two charged particles varies directly as the product of their charges and inversely as the square of the distance between them.

Coulomb's Law
