11 Formulas Flashcards
1
Q
Flow of charge
A
Flow of charge = current x time
2
Q
Current
A
Current = charge / time I = Q / t
3
Q
Voltage
A
Voltage = energy / charge
4
Q
1 volt
A
1 volt = 1 joule / 1 coloumb
5
Q
Resistance
A
Resistance = voltage / current
6
Q
Ohm’s law
A
resistance = potential difference / current
7
Q
Energy transfer
A
Energy transferred = charge moved x potential difference
8
Q
Power (3)
A
P = I x V P = I^2x R P = E / t
