Q. In dynamic braking, when braking is applied system acts as

  • (A) freely running machine
  • (B) motor with slow speed
  • (C) generator
  • (D) motor with same speed in opposite direction

βœ… Correct Answer: (C) generator
Explanation: the armature is disconnected from the supply and then a braking resistor rb is immediately connected across it. the motor acts as a generator, driven by the inertia and stored kinetic energy dissipating power in rb. this is a simple method of bringing a motor nearly to a standstill.
