Question

The applied input ac power to a half wave rectifier is 100 watts. The d.c output power obtained is 40 watts. What is the rectification efficiency?​

Answer 1

Answer:

$rectification \: efficiency = 80 \: \%$

Explanation:

We know that,

theoretical Output power of half wave rectifier is half of applied input AC power.

$theoretical \: output \: power = \frac{100}{2} = 50 \: watts$

$rectification \: efficiency = \frac{dc \: output \: power}{theoretical \: output \: power} \times 100 \: \%$

$rectification \: efficiency \\ = \frac{40}{50} \times 100 \: \%$

$rectification \: efficiency \\ = 80 \: \%$
