उत्तर
To convert a moving coil galvanometer into an ammeter we need to connect a small resistance in parallel with it.
Explanation:
To turn a moving coil galvanometer into an ammeter, a low-resistance, known as a shunt, is connected parallel to the galvanometer. The shunt allows the majority of the current to bypass the galvanometer, allowing it to measure high currents without being harmed. This ensures that the galvanometer deflection is proportional to the total current in the circuit.
