Magnetic Effects Of Current Question 459
Question: 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
Options:
A) 0.001
B) 0.01
C) 1
D) 0.05
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Galvanometer is converted into ammeter, by connected a shunt, in parallel with it. $ \frac{GS}{G+S}=\frac{V_{G}}{I}=\frac{25\times {{10}^{L_{3}}}}{25} $ $ \frac{GS}{G+S}=0.001\Omega $ Here $ S«G $ so $ S=0.001\Omega $
