Solution

Resistance:
It is the tendency of a material by which it resists the flow of charge through it.
Its unit is ohms $Ω$ .
Current:
It is the rate at which charge flows through a material.
Its unit is ampere $A$ .
Power:
It is the rate at which work is done.
It is the product of square of current and resistance. It is given as $P = I^{2} R$ .
So, the unit of power is $A^{2} Ω$ .
Hence, $A m p e r e^{2} o h m$ is the unit of power.
