Electrical Machines Neglecting all losses, the developed torque (T) of DC separately excited motor, operating under constant terminal voltage is reduced to its output power (P) as T is independent of P. T2 ∝ P3. T ∝ P. T ∝ √P. T is independent of P. T2 ∝ P3. T ∝ P. T ∝ √P. ANSWER DOWNLOAD EXAMIANS APP
