Write ohm\'s las. Derove a mathematical expression for it

1.	Write ohm\'s las. Derove a mathematical expression for it
Answer» The electric current flow through a conductor is directly proportional to the potential difference across the ends of the conductor and the condition is temperature should always remain constant.V proportional to ITo remove prop. use constant as R (resistance) we get V = IR hence it is the mathematical exp. of ohm\'s law.
