If the maximum efficiency of a full wave rectifier is \(\mathrm{x} \%\) and that of half wave rectifier is \(\mathrm{y} \%\), then the relation between \(\mathrm{x}\) and \(\mathrm{y}\) is
- A \(\mathrm{x}=\mathrm{y}\)
- B \(y=2 x\)
- C \(x=2 y\)
- D \(y=4 x\)
Answer & Solution
Correct Answer
(C) \(x=2 y\)
Step-by-step Solution
Detailed explanation
Maximum efficiency of full wave rectifier \(x=81.2 \%\)
Maximum efficiency of half wave rectifier \(y=40.6 \%\)
\(\therefore \quad \frac{x}{y}=\frac{2}{1}\)
Then, relation between \(\mathrm{x}\) and \(\mathrm{y}\) is \(\mathrm{x}=2 \mathrm{y}\).
Maximum efficiency of half wave rectifier \(y=40.6 \%\)
\(\therefore \quad \frac{x}{y}=\frac{2}{1}\)
Then, relation between \(\mathrm{x}\) and \(\mathrm{y}\) is \(\mathrm{x}=2 \mathrm{y}\).
