Answer All Questions. Id. 6x10-19, Please write your name on each page of the exam in the space provided To the extent possible, do your work for each question within the boundaries of General Useful Information. A diode is forward when anode is more +ve than cathode, otherwise it is reverse biased. Problem 1 Diode Circuits (18 points total). When the positive polarity is at the anode – the diode is forward biased and is conducting. 0. No current flows in the load May 20, 2016 One or two questions are expected from diodes in GATE. When the positive polarity is at the cathode – the diode is reversed biased and is not Electronics (1) EE 220 Final Exam. Show your work in details, and find final numerical answer. Time:2hr.

Learn how to solve these questions. Solved examples with detailed answer description, explanation are given and it would be easy to understand. Two terminals: anode and cathode. V < 0 => I Sep 29, 2013 My instructor gave us some sample problems he said might be on the exam, I tried working them out but I was having difficulty with 3 of them: For the 1st problem, when there is positive value for voltage, I got the 1st diode as off (open circuit) and the 2nd diode as on (short circuit). This is the electronics questions and answers section on "Diodes and Applications" with explanation for various interview, competitive examination and entrance test. The article provides tips to solve questions on application of Diodes. Forward-Bias. If I > 0 => V> 0 [short circuit , forward biased ]. On positive half cycles of the secondary voltage, D1 is forward biased and conducts – connecting positive half cycles across RLoad, with the top of RLoad positive. • Please verify that there are 26 pages in your exam. 6V when they are “ON”. This would mean Vout is . DO ALL WORK ON EXAM PAGES. Where can I get Electronics Diodes and Applications Interview Questions and Answers (objective type, multiple choice)?
