1

## Conductors

### Materials in which charge can flow

2

## Insulators

### Materials in which charge cannot flow

3

## Current

###
-symbol ( I )

-measured in ( A ) (ampere) (amp)

-electrons move from the negative terminal to the positive terminal

4

## Voltage

###
-Sign ( V )

-measured in ( V ) ( the Volt )

-the amount of electrons used to go through a circuit

5

## Difference between current and voltage

###
-voltage : amount of electrons needed to get through the circuit

-current: the movement of electrons from the negative to positive terminals of a battery

6

## Resistance

###
-sign ( R )

-measured in the ( error 404: symbol not found ) (Ohm)

-the opposition of flow along a wire

Eg. Copper has a low resistance, silver high resistance

7

## Ohm laws

### -voltage is directly proportional to current

8

## Triangle for calculating variables in electricity

###
V

--------

I X R

9

## Bulbs in series

### -if one goes the whole circuit will be stopped

10

## Bulbs in parallel

###
Is one goes the other will still shine bright like a diamond
