Full Wave Rectifier Output Frequency – Rankers Physics

P-N Junction Diode and its applications: Practice Problem & Solution

Assertion (A): Output frequency of time varying DC voltage in a full wave rectifier is twice of input frequency. Reason (R): A center tap transformer increases the frequency of input.
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of P-N Junction Diode and its applications. Understanding the underlying formula is key to arriving at the correct answer below:

A full-wave rectifier converts both halves of an AC input into a pulsating DC output, effectively doubling the input frequency. Thus, Assertion (A) is true. A transformer only steps up or steps down voltage and current; it does not alter the frequency of the AC signal. Hence, Reason (R) is false.
