The maximum current that can be measured...

The maximum current that can be measured by a galvanometer of resistance 40 is 10 mA. It is converted into a voltmeter that can read upto 50 V. The resistance to be connected in series with the galvanometer is ........ (in ohm)

A

2010

B

4050

C

5040

D

4960

Text Solution

Verified by Experts

The correct Answer is:
D

The value of resistance to be connected in series with galvanometer is
`R=(V)/(I_(g))-G=(50)/(10xx10^(-3))=40`
` =5000-40=14960Omega`.
