Write the expression for the instantaneous values of EMFs in a 3-phase circuit. Answer : In a 3-phase circuit, the instantaneous values of the Electromotive Forces (EMFs) in the three phases can be expressed as sinusoidal functions, assuming a balanced system where the phases are 120° ... , these expressions show how the voltages in each phase are related in both magnitude and phase....
