A full wave rectifier passes _ into positive cycles:
Correct answer: C. Both lower and upper half cycles
- A. Lower half cycle
- B. Upper half cycle
- C. Both lower and upper half cycles
- D. One quarter cycle
Explanation
c) Both lower and upper half cycles: This option is correct. A full-wave rectifier passes both the lower (negative) and upper (positive) half cycles of an AC input waveform. It does so by using a bridge rectifier circuit or by employing multiple diodes to ensure that the entire AC waveform is converted into a unidirectional (DC) output.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
