Flashcards in vocabulary Deck (19):

1

## switch

### opens and closes a circuit

2

## electric charge

### a fundamental property of matter; there are two types- positive(+) and negative (-)

3

## open circuit

### a circuit in which there is a break in the wire so that current cannot flow

4

## closed circuit

### a circuit in which the switch is turned to the "on" position causing there to be no breaks in the circuit

5

## electrostatic force

### the force that exists between electric charges

6

## coulombs law

### as 2 charged objects get closer, the force between them increases

7

## coulomb

### the unit for electrical charge

8

## current

### the quantity that refers to the rate of flow of electric charges

9

## insulator

### something that blocks the flow of electric current

10

## conductor

### a metal; a material that energy can easily flow through

11

## voltage

### the amount of potential energy that each unit of electrical charge has; 1 volt= 1 joule/ 1 coulomb

12

## electrical conductivity

### the ability of a material to conduct electricity

13

## battery

### a device that uses chemical energy to move electrical charges

14

## resistance

### the measure of an objects ability to conduct current

15

## ohms law

### describes the mathematical relationships present in most circuits

16

## series circuit

### a circuit in which the current only has one path

17

## parallel circuit

### a circuit in which the current can take more than one path

18

## short circuit

### a branch in a circuit with zero/very low resistance
