In the circuits (a) and (b) switches $\displaystyle \mathrm{S}_1$ and $\displaystyle \mathrm{S}_2$ are closed at $\displaystyle \mathrm{t}=0$ and are kept closed for a long time. The variation of currents in the two circuits for $\displaystyle \mathrm{t} \geq 0$ are roughly shown by (figures are schematic and not drawn to scale) :
