The correct answer is:
$y=2 x$
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 $\mathrm{x}=2 \mathrm{y}$.
