Rectifiers & Filters

If the maximum efficiency of a full wave rectifier is $x\%$ and that of half-wave rectifier is $y\%$ , then the relation between $x$ and $y$ is

Show answer and solution

Answer: (b)

Maximum efficiency: half-wave $\eta = 40.6\%$ , full-wave $\eta = 81.2\%$ .
$x = 81.2 = 2 \times 40.6 = 2y$ .
So the answer is (b) $x = 2y$ .
