Answer» Net emf`=E_(2)-E_(1)`, total resistance `=R+r_(1)+r_(2)` Current in the circuit is `I=((E_(2)-E_(1))/(R+r_(2)+r_(1)))=(4.0-2.0)/ (5.0+1.0+2 .0)=0.25A` (from C to A via B) (i) Potential difference between the points B and `A= V_(B)-V_(A)=E _(1)+Ir_(1)=2+0.25xx1=2.25V` (ii) Potential difference between the points A and C =potential drop across `5Omega=5xx0.25=1.25V` |
