The coil of a moving-coil galvanometer keeps on oscillating for a long time if it is deflected and released. If the ends of the coil are connected together, the oscillation stops at once. Explain.
If the two ends of the coil of the moving-coil galvanometer is connected together, then it will act as a closed loop. thus, the coil no longer acts as an inductor. Therefore, all oscillations stop at once.
While If the ends of the coil are not connected, then the coil will act as an indicator, it will oscillate up to the current in it decays slowly.
