1.	DC power output of bridge full wave rectifier is equal to (Im is the peak current and RL is the load resistance).(a) 2 Im^2RL(b) 4 Im^2RL(c) Im^2RL(d) Im^2 RL/2I had been asked this question in examination.The doubt is from Bridge Rectifier in section Application of Diodes of Electronic Devices & Circuits
Answer» CORRECT answer is (b) 4 Im^2RL The EXPLANATION is: DC output power is the power output of the rectifier. We know VDC for a bridge rectifier is 2Vm and IDC for a bridge rectifier is 2Im. We also know VDC=IDC/RL. Hence output power is 4Im^2RL.
