The relationship between the torque(T) and power(P) developed in the DC shunt motor is ___________ (Neglecting all the losses)

(a) T ∝ √P

(b) T ∝ P^2

(c) T ∝ ∛P

(d) T ∝ P

I got this question during an interview.

I need to ask this question from Countercurrent Braking of DC Shunt Motors in section Braking of DC Motors & Induction Motors of Electric Drives

Correct choice is (d) T ∝ P

The explanation is: The torque developed in the DC shunt motor is the ratio of power developed and angular

speed of the motor. T=EbIa÷ωm=P÷ωm. T ∝ P.
