Question

Figure shows a full-wave rectifier with a smoothing capacitor. The currents $I_1$ and $I_3$ vary with time as shown in figure next. Which of the graphs $a-d$ shown in fig best represents the variation of the current $I_2$ with time?

(d) : From Kirchhoff's law, $I_1+I_2=I_3$ Hence, $I_2=I_3-I_1$
