The current in an object at constant temperature is proportiinal to the potential difference accross it's end .The ratio of potential difference to current is a resistance of object . The object must be at constant temperature for the law to apply since , a current is help it up and this will change its resistance Ohm's law mathematically states that - v/I = R = constant V=IR where v is variation between potential difference , I is current and R is resistance of conductor

At constant temperature, The potential difference across the conductor is directly proportional to the amount of current flowing through it .
V = IR
I = V/R
