Decreasing the resistance of an ammeter's shunt resistance
A) enables more current to pass directly through the galvanometer.
B) converts it to a voltmeter.
C) allows it to measure a larger current at full scale deflection.
D) allows it to measure a smaller current at full scale deflection.

Question

Quizplus · Accepted Answer

Decreasing the shunt resistance in an ammeter allows more of the total current to bypass the galvanometer coil, enabling the ammeter to measure larger currents without reaching its full scale deflection too quickly. This is because the shunt provides an alternative path for the current, reducing the burden on the galvanometer.
