1. OMH’S LAW
The current flowing through the circuit is directly proportional to the applied voltage an inversely proportional to the resistance of the circuit.
I ~ V
I ~ 1 R
I = V
V = Voltage of the circuit measured in Volts (V)
I = Current through the circuit measured in amperes (A)
R = Resistance measured in Ohms (Ω)
