In the circuit shown in the figure `R_(1) =3 Omega,R_(2) = 2 Omega and R_(3) = 5 Omega` Emf of the cell `epsilon = 6` Volt.
(a) Infinitely many `1 Omega` resistors are added in parallel to `R_(1) and R_(2)`. Find current through `R_(2)` and potential drop across it.
(b) Infinitely many `1 Omega` resistors are added in series to `R_(3)`. Find the potential drop across `R_(3)` and current through it.
