हिन्दीCurrent sensitivity of a moving coil galvanometer is \( 5\text{ div/mA} \) and its voltage sensitivity (angular deflection per unit voltage applied) is \( 20\text{ div/V} \). The resistance of the galvanometer is
Correct answer · Option 3
\( 250\text{ }\Omega \)
Explanation
Resistance \( R = \frac{I_s}{V_s} = \frac{5\text{ div/mA}}{20\text{ div/V}} = \frac{5 / 10^{-3}}{20} = \frac{5000}{20} = 250\text{ }\Omega \).
