In a galvanometer, 5% of the total current inthe circuit passes through it. If the resistance ofthe galvanometer is G, the shunt resistance 5connected to the galvanometer is
A) 19 G
B)\[{{r}^{7/2}}\]
C) 20 G
D) \[{{r}^{5/2}}\]
Correct Answer:
B
Solution :
Current in galvanometer \[{{E}_{ph}}\] \[\frac{{{E}_{e}}}{{{E}_{ph}}}\]
