To convert a galvanometer to a voltmeter, a
A
high resistance is connected to it in series
B
high resistance is connected to it in parallel
C
low resistance is connected to it in parallel
D
low resistance is connected to it in series
Verified Correct Answer: A.
Physical Principles & Numerical Solution
To convert a galvanometer (which measures current) into a voltmeter (which measures voltage), a high resistance is connected in series with the galvanometer. This limits the current flowing through the galvanometer, allowing it to measure higher voltages without exceeding its maximum current rating.
