Q: In a moving coil galvanometer, what is the role of the spring?
Solution: The spring in a moving coil galvanometer provides a restoring torque that returns the coil to its original position when the current is removed.
Steps: 6
Step 1: Understand what a moving coil galvanometer is. It is a device used to measure electric current.
Step 2: Know that the galvanometer has a coil that moves when electric current passes through it.
Step 3: Recognize that when the coil moves, it can go out of its original position.
Step 4: Learn that the spring is attached to the coil.
Step 5: Understand that the spring pulls the coil back to its original position when the current stops.
Step 6: Realize that this pulling action is called restoring torque.
