1

Define current

The rate of flow of the charge

2

What is the equation Current

Current = charge/time

3

What is the equation for potential difference ?

V = ENERGY / CHARGE

4

What is the equation for electric charge

Q = I x t

5

What is the equation for resistance ?

R = V/I

6

What is current measured in ?

Amps

7

How many electrons make up -1c of charge ?

How many = Total / value of each

8

Define voltage

The measure of the energy difference each coulomb has between two points

9

What is energy used for ?

Used in a electrical circuit

10

Equation for Energy

Energy = power x Time
E = P x T

11

Equation for power ?

W = Energy / Time

12

What is 1 kW = too ?

1000 W

13

What is the equation for energy transferred ?

J = Charge flow x potential difference

14

What is Ohms law ?

Ohms law states in a circuit the voltage across component is directly proportional to the current , provided temperature is constant

15

What is the equation for Ohms law

V = I x R

16

What is the equation for resistance in terms of Ohms law ?

Resistance = Voltage / current

17

What is the equation for Potential difference in terms of series and parallel circuits ?

Potential difference = Current x resistance
