Electrical work W = QE, Where Q is the quantity of change and E is the electromotive force. ∴ E = W = FxDQ_It Where D is the displacement,I = current and t = time But dimension of force, = unit of mass x unit of Acceleration = unit of mass xunit of velocityunit of time = unit of mass x unit of displacement__unit of time x unit of time ML/T2 = MLT-2 ∴ Dimension of emf E = MLT-2L = ML2T-3I-1__IT
