Vedclass · Answer

(A) In a bridge rectifier circuit,the $AC$ input is applied across two opposite junctions of the diode bridge,while the $DC$ output is taken across the other two opposite junctions.Looking at the provided figure,the diodes are arranged such that they point towards $A$ and $D$ from $B$ and $C$ respectively. To achieve full-wave rectification,the $AC$ input must be connected across the junctions $B$ and $D$. When the input is applied at $B$ and $D$,the $DC$ output is obtained across the junctions $A$ and $C$. During the positive half-cycle of the $AC$ input,two diodes conduct to provide current in one direction through the load,and during the negative half-cycle,the other two diodes conduct to provide current in the same direction through the load. Thus,the correct configuration is $AC$ input across $B$ and $D$,and $DC$ output across $A$ and $C$.

For the circuit shown in the adjoining figure,to act as a full-wave rectifier,the $AC$ input should be connected across $....$ and $....$ and the $DC$ output would appear across $....$ and $....$.
