Drive the dimensions of potential, current density, inductance and resistivity in the SI system?

he expression for the mean torque (T) of an electrodynamics wattmeter may be written as:

T α M^{a} V^{b }Zc where:

M is the mutual inductance mutual inductance between coils,

V is the applied voltage and Z is the load impedance.

From the dimensions of quantities involved determine a, b and c.
