What are the 3 forms of Ohm's law?

There are three forms of Ohm’s law that relate to voltage, current, and resistance. For a constant flow of current, the current is given by the ratio of voltage across terminals to the resistance of the resistor.

I = V/R

Ohm’s law can also be written as

R = V/I

V = IR

I is the current
V is the voltage
R is the resistance

Read the following paragraph and answer the questions that follow.
A p-type or n-type semiconductor can be converted into a p-n junction by doping it with suitable impurity. The motion of majority charge carriers causes diffusion current across the junction while the barrier electric field causes motion of minority carriers for drift current. In case of unbiased diode, the diffusion and drift currents are equal. This equilibrium is disturbed by the biasing batteries. Diodes, therefore, allow currents in one direction. This property of diode is used in making rectifiers.
