alleryTo convert a galvanometer to a VOLTMETER, connect:
AA shunt in parallel
BA high resistance R in SERIES
CNothing — galvanometer is already a voltmeter
DA capacitor in series
Answer & Solution
Correct answer: B. A high resistance R in SERIES
Voltmeter requires high resistance so it doesn't draw much current from the circuit.
Series high resistance R = V/I_g - G converts the galvanometer to measure V.
