What is the function of the control springs in a PMMC galvanometer?
Right Answer is:
To serve as conductors and provide restoring force
SOLUTION
The function of the control springs in a Permanent Magnet Moving Coil (PMMC) galvanometer is to serve as conductors and provide restoring force.
- Controlling Torque: The springs provide a controlling torque that opposes the deflecting torque, ensuring the pointer returns to its zero position when the current is removed.
