The turns ratio of a transformer used in half wave rectifier is 20:1.

Question

The turns ratio of a transformer used in half wave rectifier is 20:1. The primary is connected to the power mains: 220 V, 50 Hz. If the diode resistance in forward bias is 20 and the load resistance, RL is 500 , determine

i) the peak value, the dc value and the rms value of current

; ii) the ripple factor; and

iii) the rectification efficiency

i) Peak Value, DC Value, and RMS Value of Current:

For a transformer with a turns ratio of 20:1, the secondary voltage \( V_s \) can be calculated as:

\[
V_s = \frac{V_p}{\text{turns ratio}} = \frac{220\ V}{20} = _________ ______ _______ __________ __________ ____ _________ ________ ____ _________ ______ __________.
