In an energy meter, braking torque is produced to Correct Answer Maintain steady speed and equal to driving torque

  • In an energy meter, a braking torque is produced to maintain a steady speed and equal to driving torque
  • A permanent magnet positioned near the edge of the aluminium disc from the braking system
  • The aluminium disc (shown in the figure) moves in the field of this magnet and thus providing the braking torque
  • The position of the permanent magnet is adjustable, and therefore, braking torque can be adjusted by shifting the permanent magnet to different radial positions

Select the option that is true regarding the following two statements labeled Assertion (A) and Reason (R). Assertion (A): Whenever we measure an electrical signal, there are chances of over current which leads to overheating of the meter. In such cases, the meter can be protected by using a semiconductor diode of suitable rating. Reason (R): As soon as the diode is short-circuited, the meter current is diverted through the diode. As a result, the meter is being protected from excess heating.
