Question

The dimesions of emf in MKS is

Answer 1

Answer:

The dimension formula of EMF in MKS unit system is [M^1L^2T^-3I^-1] unit.

Explanation:

Electromotive Force and Internal Resistance. The electromotive force (e) or e.m.f. is the energy provided by a cell or battery per coulomb of charge passing through it, it is measured in volts (V). It is equal to the potential difference across the terminals of the cell when no current is flowing.

e = E / Q

where,

e = Electromotive force in volt (V)

E = Energy in joule (J)

Q = Charge in coulombs (C)

The dimentional formula of Electromotive Force is [M^1L^2T^-3I^-1] Volt.
