Electrical Engineering XYZ MCQs

In a DC motor under constant terminal voltage the relation between torque (Te) and power (P) is given as:

  1. T is independent of P
  2. T∝ P²
  3. T∝ P³
  4. T∝ P

Correct answer: 4. T∝ P

Explanation: In a DC motor under constant terminal voltage the torque (Te) is directly proportional to power (P).
