State ohms law. Also prove it mathematically

1.	State ohms law. Also prove it mathematically
Answer» According to the Ohm\'s law, a German scientist observed stated that potential difference(V) is directly proportional to the current(I) and resistance (R). Therefore V=IR According to this law the Voltage established across the two ends of wire is directly proportional to the current flowing through it. According to ohms law potential difference of a battry is directly proportional to current in a circuitV propn I ( v is volt and i is current)V=RI (here R is constant)
