Current sensitivity of a moving coil gal...

Current sensitivity of a moving coil galvanometer is 5 div/mA and its voltage sensitivity (angular deflection per unit voltage applied) is 20 div/V. The resistance of the galvanometer is

A

250 `Omega`

B

25 `Omega`

C

40 `Omega`

D

500 `Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
Voltage per division `= (1)/(20)V`
Current per division = `(1)/(5000)V`
`R = (V)/(1) = ((1)/(20))/((1)/(5000)) = 250 Omega`
