WebWhat is shunt explain its function? A shunt is a low resistance connected in parallel to a circuit element. Functions of the shunt : (1) It lowers the effective resistance of the ammeter. (2) It shunts off a larger fraction of the line current, thus protecting the sensitive meter movement of the basic galvanometer.
