For full scale deflection of total 50 divisions, 50 mV voltage is required in galvanometer. The resistance of galvanometer if its current sensitivity is 2 div/mA will be:

A

`1 Omega`

B

`2 Omega`

C

`4 Omega`

D

`5 Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
Current sensitivity = 2div/mA
So full scale current `=50/2` mA
= 25 mA
Full scale voltage = 50 mV
So, Resistance `=V/I = 2 Omega`
