If a full wave rectifier circuit is operating from \(50 \mathrm{~Hz}\) mains, the fundamental frequency in the ripple will be

  1. A \(70.7 \mathrm{~Hz}\)
  2. B \(100 \mathrm{~Hz}\)
  3. C \(25 \mathrm{~Hz}\)
  4. D \(59 \mathrm{~Hz}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(100 \mathrm{~Hz}\)

Step-by-step Solution

Detailed explanation

For full wave rectifier, ripple frequency
\(=2 \times\) input frequency
\(
\begin{array}{l}
=2 \times 50 \\
=100 \mathrm{~Hz}
\end{array}
\)
Note A full wave rectifier consists of two junction diodes, so, its efficiency is twice that of half wave rectifier.
