1.	The diode in a half wave rectifier has a forward resistance RF. The voltage is Vmsinωt and the load resistance is RL. The DC current is given by _________(a) Vm/√2RL(b) Vm/(RF+RL)π(c) 2Vm/√π(d) Vm/RLI had been asked this question by my college director while I was bunking the class.The doubt is from Half-Wave Rectifier topic in chapter Application of Diodes of Electronic Devices & Circuits
Answer» CORRECT ANSWER is (B) VM/(RF+RL)π The explanation is: For a half wave RECTIFIER, the IDC=IAVG=Im/π I= Vmsinωt/(RF+RL)=Imsinωt Im =Vm/ RF+RL So, IDC=Im/π=Vm/(RF+RL).
