Question

state Ohm's law mathematically

Answer 1

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

Answer 2

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
