A moving coil galvanometer has 150 equal divisions. Its current sensitivity is 10 divisions per milliampere and voltage sensitivity is 2 divisions per millivolt. In order that each division reads 1 volt, the resistance in ohms needed to be connected in series with the coil will be

Options:

Answer:

D

Solution:

$I_{g} = 15 mA V g = 75 mV$ $R = \frac{V}{I _{g}} - \frac{V _{g}}{I _{g}}$
