Professor PC Thomas Classes · Answer

(d) : An ammeter is used to measure current and is connected in series with the circuit branch of interest. To ensure it doesn't significantly alter the current it's measuring, its overall resistance must be very small. Therefore, a very low resistance (called a shunt) is connected in parallel with the galvanometer. This provides an alternate low-resistance path for the majority of the current, protecting the sensitive galvanometer coil.
