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) MAGIC TRIANGLE Pheelwane KA
