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.
Current decreases When voltage remains constant and resistance increases the current in the circuit will reduce. More information V=IR where V is voltage, I is current an â¦ d R is resistance. From the above equation, R=V/I, and hence resistance is indirectly proportional to current.
