A micro-ammeter gives full scale deflection at `100muA.` Its resistance is `2KOmega` The resistance required to convert it to a voltmeter reading 1V is

A

`1 kOmega` in series

B

`8k Omega` in series

C

`1 kOmega` in parallel

D

`8 k Omega` in parallel

Text Solution

Verified by Experts

The correct Answer is:
B

`l xx R =(0.8 V)`
`10^(-4) xx R = 0.8`
`R = (8 xx 10^(3) Omega)` in series.
