1.	What is the ripple factor for a half-wave rectifier?(a) 2.0(b) 1.21(c) 0.482(d) 0.877I got this question during an interview for a job.This intriguing question originated from Semiconductor Electronics topic in section Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12
Answer» Right choice is (b) 1.21 Best EXPLANATION: For a half-wave RECTIFIER, Irms=\(\FRAC {I_m}{2}\); IDC=\(\frac {I_m}{\pi }\) r = \(\sqrt {\frac {(\frac {I_m}{2} )^2}{(\frac {I_m}{\pi } )^2} – 1}\) r=1.21
