A galvanometer of resistance 20Omega is ...

A galvanometer of resistance `20Omega` is shunted by a `2 Omega` resistor. What part of the main current flows through the galvanometer ?

Text Solution

Verified by Experts

`(i_(g))/(i)=(G)/(G+S).` Given `G=20Omega, S=2Omega`
`:. (i_(g))/(i)=(2)/(22)=(1)/(11),(1)/(11)th` part of current is passing through galvanometer.
