According to statement I and II, full wave rectifier with capacitor and inductor are as shown in figure.
In figure (A), the capacitor is connected in parallel to load resistance
(RL), as it can block DC current.
∴ DC current can pass only through
RL which gives DC output.
In figure (B), as the AC current is time varying current which can produce an opposition in current due to inductor that cancel the effect of AC in the load resistance (
RL).
Hence, pure DC output is obtained across
RL.
Hence, statement I and statement II are true.
