A voltmeter of range `0-10V` and resistance `200 Omega `cannot be used as an ammeter, whose range is

A

`0-500 mA`

B

`0-250 mA`

C

`0-100 mA`

D

`0-25 mA`

Text Solution

Verified by Experts

The correct Answer is:
D
Current through te voltmeter (I)`V/R=10/200=1/20A=50mA` It cannot be converted into an ammeter of current range less than 50 mA. If a shunt is used current range will increases.
