What is the function of a galvanometer in a circuit ?
Answer
A galvanometer detects the presence of an electric current in a circuit and shows its direction.
A galvanometer detects the presence of an electric current in a circuit and shows its direction: its pointer stays at the central zero when no current flows and deflects to one side or the other according to the direction of the current.
