In a half-wave rectifier, the peak value of the ac voltage

Home » Physical Electronics Devices and ICs » Physical electronics devices and ics miscellaneous » Question

In a half-wave rectifier, the peak value of the ac voltage across the secondary of the transformer is 20 V. If no filter circuit is used, the maximum dc voltage across the load will be—

1. 28.28 V
2. 20 V
3. 14.14 V
4. 9 V

Correct Option: C

V_rms =	V_m
	√2

V_rms =	20 √2	= 20 V
	√2
