Vedclass · Answer

(C) The total resistance of the voltmeter is $R_{total} = R_g + R_s = 80 \Omega + 920 \Omega = 1000 \Omega$.The full-scale deflection current is $I_g = 10 	ext{ mA} = 0.01 	ext{ A}$.The maximum voltage $V_{max}$ that the voltmeter can measure is given by $V_{max} = I_g 	imes R_{total} = 0.01 	ext{ A} 	imes 1000 \Omega = 10 	ext{ V}$.The least count of the voltmeter is given as $0.2 	ext{ V}$ per division.The number of divisions $N$ is calculated as $N = \frac{V_{max}}{	ext{Least Count}} = \frac{10 	ext{ V}}{0.2 	ext{ V/division}} = 50 	ext{ divisions}$.
