Q.
In bridge rectifier circuit, (see fig.), the input signal should be connected between
Semiconductor Electronics: Materials Devices and Simple Circuits
Solution:
The input signal should be connected between two points of bridge rectifier such that in positive half wave of input signal, one p-n junction should be forward biased and other should be reverse biased and in negative half wave of input signal, the reverse should take place. It will be so when input is connected between $B$ and $D$.
