Lecture – 2 Electronic Devices 1

In the last lecture we saw the importance of learning about electronics, method of learning by doing, how it is very useful learning a subject like electronics and a brief history of electronics, about various stages like the vacuum tube, the transistor and integrated circuits. We also saw the plan of the topics to be…

Lecture – 3 Electronics Devices

Lecture – 3 Electronics Devices

Hello everybody we are doing a course on basic electronics electronics by the method of learning by doing. We saw in the previous lecture about different types of resistors; fixed resistors, variable resistors which are also called potentiometers and some special type of resistors which are called for example LDR light dependent resistors whose resistance…

Pininfarina Batista the Pininfarina Batista is a Mahindra owned electric hyper car which is reputed to be even speedier than a Formula one racer this vehicle lives up to its fearsome reputation with 1,900 horsepower and 2300 Newton meters of torque with zero emissions which propels the Bautista to speeds of 100 km/h in less…

Optoelectronic devices: Introduction

Optoelectronic devices: Introduction

In the last few classes, we have looked at Electronic devices. So, we first started looking at a Metal Semiconductor contact, forms your Schottky junction or an Ohmic junction. We then looked at p-n junctions and then finally, transistors. We saw that there were different kinds of transistors, but we focused on the metal oxide…

Lecture-19-PN Junction

Lecture-19-PN Junction

In the last 18 lectures we have discussed the basics of semiconductors. We considered the equilibrium carrier concentration then we considered Excess Carriers. We saw how the carriers move in response to electric field and concentration gradients, then we saw how we can translate all these basic understanding into five differential equations which described the…
