GATE EE 1992

MCQ (Single Correct Answer)

-0.3

Neglecting all losses, the developed torque $$(T)$$ of $$d.c.$$ separately excited motor, operating under constant terminal voltage, is related to its output power $$(P)$$ as under

$$T\,\, \propto \,\,\sqrt P $$

$$T\,\, \propto \,\,P$$

$${T^2}\,\, \propto \,\,{P^3}$$

$$T$$ independent of $$P$$
