Q1.
a and b are in series.
net resistance=R+R=2*R
it is in parallel with c.
net resistance=2*R*R/(2*R+R)=2*R/3
it is in series with d.
net resistance=5*R/3
it is in parallel with e.
net resistance =(5*R/3)*R/((5*R/3)+R)
=5*R/8
it is in series with f.
so total resistance of the circuit=R+(5*R/8)
=13*R/8
current in the circuit=V/(13*R/8)
=14/(13*3.25*1000/8)=2.651 mA
current through f=2.651 mA
e and (5*R/3) are in parallel.
using current division , current through=e=2.651*(5*R/3)/((5*R/3)+R)
=2.651*5/8 mA=1.6569 mA
current through 5*R/3 =2.651-1.6569=0.9941 mA
d is in series with 2*R/3 to create 5*R/3
so current through d=0.9941 mA
using current division
current through c=0.9941*2*R/(2*R+R)=0.6627 mA
current through a=current through b=0.9941-0.6627=0.3314 mA
potential difference between A and B=-R*current through c
=-3.25*1000*0.6627*0.001=-2.1538 volts
