Subject: Electronics Devices & Circuits/ Basic Electronics Engineering Chapter: Semiconductor Diode and its Applications Topic: Diode circuit related numerical solution (calculation of diode voltage and current, diode equation related problems, temperature related problems, calculation of small signal dynamic resistance, change in diode current and voltage) Language: English (Slide) + Nepali (Explanation) In this video: 1. Find the values of diode current I and voltage across diode V in the given circuits (Solution for 6 circuits) 2. (a) In the diode circuit η=1, VD1=0.7V, ID1=1mA then for ID2=10mA.Calculate VD2. 2. (b) A silicon PN junction diode which has η=1 has V=0.7V at I = 1mA. Find the voltage drop across the diode at I=0.1mA . 3. A si diode has a saturation current of 0.1pA at 20°C. Find its current when it is forward biased by 0.55V. Find the current in the same diode when the temperature rises to 100°C. 4. A diode conducts 1mA at 20oC. If it is operated at 100oC, what will be its current? Given data are 𝜂=1.6, and negative temperature coefficient value = -2.2 mV/oC. 5. Find the value of the small signal resistance for the diode. Given VD = 0.82V, IS = 10-12 A and η=1.6. 6. Prove that diode voltage changes by 2.3ηVT when diode current changes by a decade (ten times). #diode #edc #basicelectronic #basicelectricalengineering #tutorials # #numerical #solution #diodecircuits keywords: diode circuit examples, diode circuit problems with solutions pdf, diode problems and solutions, solved problems on p-n junction diode pdf, diode circuit questions and answers, diode numerical, diode current equation, diode circuit problems with solutions pdf, diode problems and solutions, solved problems on p-n junction diode pdf, diode problems and solutions pdf, derivation of diode equation, ideal diode current equation, simple diode circuit problems, diode problems, diode circuit solution, find current flow through diode, find voltage across diode, find saturation current, find change in voltage in diode, find diode current, negative temperature coefficient, calculate diode voltage and current, numerical and solution
