FIITJEE ques

at what time instant ??
steady state or inititally ??or at any general time ??

i have a dbt whether a galvanometer read a decaying or a growing current as we know these instruments wont works on d.c .

let us cinsider after steady time as generall these questions expect this answer

simply using kirchoffs law along the path of the resistors

we get i as 0.2 now again using kirchoffs law we can use and get the answer

Now here is a small qsn, in a normal wheastone bridge, we can exchange battery and galvanometer, can we do the same here......I guess that may simplify things.

YEs the answer comes to 0.2
I dont think we can exchange it there because the G has a Resistence of 0.1 Ω \
So we cannot
