Ohm's law defines the relationship between the voltage, current, and resistance in an electric circuit: I = V / R. The current is directly proportional to the voltage and inversely proportional to the resistance.
OhmÂ´s Law. There is a relationship between Voltage, Current and Resistance. The current in a circuit (amp) is directly proportional to the applied potential difference (volts) and inversely proportional to the resistance of the circuit (resistance). I = v/r. Example: I = v/r A nine volt battery supplies power to a bulb with a resistance of 18 ohms.
