●Proof Of the elation P/Q=R/S

$\huge★Answer ↴$

●In the null condition IG=0, so, the potential different between the two ends of the galvanometer,

or, VB=VD

:.VA-VB=I1p; VA-VD=I2R

And VB-VC=I1Q; VD-VC=I2S.

Now, Since VB=VP

:.I1P=I2R...................................... (2)

:.I1Q=I2S.........................................(3)

Now Dividing equation (2) by equation (3)

$\fbox{P/Q=R/S}$
