Yes liked it very much. Did my electrical engineering about 41 years ago. This type of learning experience was not available at that time. My father wanted me to build induction furnace at that time but I didn't venture into it because of lack of clarity. I opted for the clerical job 😭😭😭

[@azeemrsetrx1024]

Dear, your videos are very easy to understand by the basic. Keep it up. 👍👍👍👍👍👍👍👍👍👍

[@ronaldhipp3223]

you should have been a teacher. i now undestand those mosfets. thank you.

[@jozsiolah1435]

It’s ideal to magnify your processors if you can, and calculate the leads from the Cpu core. Core 2 Duo has about 5-10 more leads to the motherboard, then Pentium Dual core (laptop cpus).

[@TheWeedOperation]

I don't know why people believe bjts are slower than mosfets. Principally bjts are faster than mosfets. Mainly because bjts are current devices and mosfets require charging of the gate capacitance during any transition.

[@NoSpeechForTheDumb]

Yes this drives me crazy too. It's because people are stupid and need simple messages. In fact: A MOSFET of the SAME size and overall specs as a BJT ALWAYS switches SLOWER because of the gate capacitance, but MOSFETs are generally much smaller in size, so it's all pointless to compare.

[@benyomovod6904]

All cpus are mosfet, they are faster

[@TheWeedOperation]

@@benyomovod6904 They are fast because the individual mosfets are made to be very small reducing the charge required to turn them on and off. That is one of the reasons why fabrication size reduction are so important in the chip industry. When sizes are matched, bjts tend to be faster than mosfets. The additional reason mosfets are used in cpus is because when they are fully turned on or off they don't need any additional power to stay in that state. This makes for lower power devices.

Good video, what's kind of software you are using?

[@FoolishEngineer]

[@RahulSharma-oc2qd]

Why you always use same direction of body diode in n and p channel mosfet? Don’t you think body diode orientation should change based on type of mosfet channel?

[@alexandruradu6040]

man, when MOSFET is in the ohmic region, he despite heat because rds increase with voltage from Ugs?

[@greninjadark-cu3qt]

When we include temperature in any electrical device like but and MOSFET, it will start to be "confusing". Like what Physics Law or Principle that relates temperature and resistance? Can't name one law/principle.

[@wanderingmoon9772]

So, what is but good for??

[@dawsonpate7385]

One use of mosfets is controlling power . . . I use it in a custom console of mine to control power flow between battery and charging port. While charge is applied via USB battery does not dissipate power but when USB is removed battery can now discharge to keep console running. This prevents battery discharge when plugged in

[@dumb_didi]

why switching speed of mosfet is high?

[@FoolishEngineer]

It is because of its structure

[@darshandanu9302]

Why there's diode in MOSFEt

[@absalomdraconis]

A MOSFET is essentially a combination of a BJT and a JFET. The JFET part is added by putting a layer of insulator on the BJT, and then adding a 4th electrical connection on top of the insulator, placed above the "base" region of the BJT; the insulator will let the BJT base "feel" any electric charge applied to the 4th terminal, but will not allow the electrons to go from the 4th connection to the BJT. With this 4th connection placed, the base is then tied to one of the other BJT connections, chosen so that when the MOSFET is connected normally, the base will be _forced_ off. After this is done, the 4th contact (the "gate" contact on a MOSFET) can then force a small area directly under itself to turn on, but cannot force the entire BJT on. Now, to actually answer your question, tying the BJT's base to one of the other connections has a second consequence: if you hook the MOSFET up _backwards,_ then the base and the BJT connection that it is _not_ tied to will form a diode.

[@kyawwin7020]

Hi

[@karanhiragar4587]

Sorry, But BJT is a Bipolar device...Check the full name : Bipolar Juction Transistor and Mosfet is an unidirectional device... please make it right.

[@abdulkhaliq-vk7vf]

Bro try to understand concept, He is telling only in one type, Means NPN type current flow only Collector to Emitter, But in N MOSFET current can flow both direction

[@ramlaaal]

explanation is nice but i dont understand the meaning of foolish engineer,

[@FoolishEngineer]

its still a mystery for me as well!!
