e-con Systems Project Engineer - Trainee interview questions

Technical round 1.tell about your self 2.what is voltage and current? They were expecting exact definition with real time example 3.what is resistor why we use that 4.property of inductor and capacitor 5.tell about your project(it should be in detail) 6.what is rectifier 7.draw and explain full wave rectifier 8.how to reduce the ripple content in full wave rectifier. (7 and 8th question should be explained through diagram and waveform) 9.audio amplifier power is 12w when connecting 12ohms loud speaker. Now I replace the 4ohm loudspeaker instead of 12ohm now what will be the power of audio amplifier. 10.some of circuit solving questions are there I will send later. 11.what Is D flipflop and write a truth table along with draw internal logic gate diagram. 12. Is capacitor allows dc if yes why. 13. Take 1k resistor and 0.1uf capacitor are connected in series and it is connected to 5v source now how much time required for capcitor gets fully charged. Note:capacitor voltage is also 5v 14.when 5v battery is connected to 12v capacitor how much amount of voltage is stored in the capacitor. Whether it is 5v or 12v. With reason. 15.what Is diode 16.tell types of diode 17.differnce between normal diode and zener diode 18.draw any dc circuit diagram with inductor and give explanation. 19.capacitor charging curve is exponential or linear. With reason 20.you should explain the question were asked in first round and 2 round.
