NEET Physics Question - Semiconductor Physics - P-N Junction Diode and its applications

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

Solution:

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.
