If a full wave rectifier circuit is operating from \(50 \mathrm{~Hz}\) mains, the fundamental frequency in the ripple will be
- A \(70.7 \mathrm{~Hz}\)
- B \(100 \mathrm{~Hz}\)
- C \(25 \mathrm{~Hz}\)
- D \(59 \mathrm{~Hz}\)
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.
\(=2 \times\) input frequency
