1.	Derive the formula calculating of Ohm\'s law.
Answer» According to ohm\'s law : electric current is directly proportional to the potential difference at a constant temperature which is a resistance i.e. V = RI V=IR where R is constant Ohm law can be defined the electric current flowing in a conductor is directly proportional to the potential difference across end of the conductor .I is directly proportional to th V .I = VR or V = IR where R is constan of proportional and R known as the resistance of the conductor R = V/R .
