Step-by-Step Solution
A galvanometer can be converted into an ammeter by connecting a very low resistance, known as a shunt resistance, in parallel with the galvanometer coil. This low resistance ensures that most of the main circuit current passes through the shunt, protecting the delicate galvanometer mechanism from damage while allowing the device to measure large electric currents safely without altering the total circuit current significantly.
