The value of the series resistor required to convert the above galvanometer into a voltmeter with a full range deflection of 15V is
Attached Figure / Diagram
A
985 ohms
B
990 ohms
C
995 ohms
D
1000 ohms
E
1005 ohms
Verified Correct Answer: C.
Physical Principles & Numerical Solution
The value of the resistor R = \(\frac{V_{fs}}{I_s}\) - R\(_g\)
R = \(\frac{15}{0.015}\) - 5
R = 1000 - 5 = 995\(\Omega\)
