|
|
Charge |
Q= the quantity of charge that passes a point in the circuit in one second carrying one amp
Electrical property of matter Measured in coulombs |
|
|
Electrical current |
I= the rate at which a charge flows through a point in the conductor Measured in amps I is q over t |
|
|
Voltage |
It is the amount of work down to or by a charge It is the amount of energy one c of charge has at one point in circuit compared to another V is equal to w over q |
|
|
Work |
The change or transfer of energy Measured in joules |
|
|
Static electricity |

|
|
Resistance |
Opposition to flow of charge |
|
|
