A milli voltmeter of 25 milli volt range is to be converted into an ammeter of 25 ampere range. The value (in ohm) of necessary shunt will be :
-
- 0.001
- 0.01
- 1
- 0.05
Correct Option: A
Galvanometer is converted into ammeter, by connected a shunt, in parallel with it. 
| = | = | |||||
| G + S | I | 25 |
| = | = 0.001 Ω | |
| G + S |
Here S << G so
S = 0.001 Ω
