Concept:A galvanometer is converted into an ammeter by connecting a low-resistance shunt in parallel with it.
Explanation:The diagram shows a galvanometer combined with a shunt resistor.
A shunt is a small resistance connected in parallel across the galvanometer.
Most of the current in the circuit passes through the shunt, while only a small safe current flows through the galvanometer coil.
This enables the device to measure larger currents without being damaged.
Therefore, a galvanometer fitted with a shunt acts as an ammeter.
It does not become a voltmeter, voltameter, or hypsometer in this arrangement.
Answer:B. Ammeter
