Three resistors having resistances r1, r2 and r3 are connected as shown in the given circuit. The ratio i3i1 of currents in terms of resistances used in the circuit is :

  1. r1r2+r3
  2. r2r2+r3
  3. r1r1+r2
  4. r1r1+r2.

Solution

Potential difference between B and C,

VBC=i3r3=i1×r2r3r2+r3

i3=i1×r2r2+r3
