Question

If 2% of the main current is to be passed through a galvanometer of resistance G, then resistance of the shunt required is ________________?

a.G/50

b.G/49

c.49G

d.50G

​

Answer 1

$\huge\underline\mathtt\pink{Answer}$

$=G/49$

$\huge\underline\mathtt\green{Explination}$

Req=Gx/G+x,where x being the shunt resistance.

$i_9/i=R/R_9=Gx/G+x=2/100$

$98x=2G$

$x=G/49$

.

I hope this helps you.......
