not sure if you guys gives a shit but if you guys are stoned like me atm then you can watch all the new series on Instaflixxer. Have been streaming with my brother these days =)
Sir sir neet 2022 I approaching so kindly 🙏 explain core topics of physics which are most repeatedly asked topics in neet I'm totally dependent on you sir for my preparation
Sir please explain and provide a notes on the topic is construction and working of N-channel enhancement type mosfet.Sir please as well as posible explain this topic.
What is a pn junction ? A pn junction allows current in one direction only. It blocks current in the reverse direction. When a pn junction is formed, a potential barrier designated Vo comes into existence and is typically around 0.6 to 0.7 volts for silicon junctions. When the barrier whose Vo is 0.7 volts is disturbed by applying a forward bias of say, 0.6 volts, the current increases and the increase becomes steep for small increments of the forward bias value a little greater than 0.68 volts. Large currents are observed when the forward bias is 0.69 volts which is closer to the barrier voltage of 0.7 volts. The forward bias can never exceed the potential barrier voltage nor can it bring the barrier down to zero volts. That is the reason you seldom see current vs volt graphs of pn junction diodes beyond a volt or so. How does the bias remain less than the barrier in an operational diode? The voltage bias applied drops in the bulk neutral regions of the diode. A detailed description of the pn junction with a distinct approach using surface charges, alignment of Fermi levels, creation of the barrier, the distinct processes of diffusion, drift, recombination and the influence of the electric field on the energies of electrons is provided in the following textbooks. Electrostatics and circuits belong to one science and not two, that of electricity and magnetism. To know how they are unified visit this link matterandinteractions.org/articles-talks/ and view the article 'A unified treatment of electrostatics and circuits. B. Sherwood and R.
