Question
To convert a moving coil galvanometer into an ammeter we need to connect a ______.
Options
small resistance in parallel with it
large resistance in series with it
small resistance in series with it
large resistance in parallel with it
Solution
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.
