Question

the average value of a half wave rectified voltage with a peak value of 200v is

Answer 1

Given , Peak value is 200V
Relation between average value and peak value of a half wave is given by
$\bold{V_{av}=\frac{2V_{peak}}{\pi}}$
Now, Vav = 200 × 2/3.14
= 200 × 0.636
= 127.2 V

Hence, average value = 127.2V

Answer 2

the peak value of 200v is

127.3V
