Pawan is connected a galvanometer
WebWorking Principle of Galvanometer. The main function of the galvanometer is to decide the existence, direction, as well as electric current strength in a conductor. This works on the rule of converting energy from electrical to mechanical. Once the current supplies in a magnetic field, a magnetic torque can be experienced. WebTo convert a moving coil galvanometer to an ammeter, we add a low shunt resistance, but why? The shunt resistance carries the excess current, ensuring the right amount of current through the galvanometer. Created by Mahesh Shenoy.
