If the synchronous machine is connected to an infinite bus of constant voltage Vt, through a transformed, a transmission line of reactance ‘X’. Then power for a cylindrical machine is?

A. P = (Ef*Vt sinδ)/(Xs + X)
B. P = (Ef*Ef sin2δ)/(Xs + X)
C. P = (Ef*Vt sinδ)/(Xs – X)
D. P = (Vt*Vt sinδ)/(Xs + X)
Answer» B. P = (Ef*Ef sin2δ)/(Xs + X)
