Haven’t learned much in my electronics class that I took a year ago and I’m so lost in electronics 2 now and here he is saving me again. This man is a genius and has a gift for teaching others 🙌🏻

      15 years ago a Darlington transistor pair popped up on the 10th question of my 80 question Master Electrician exam. I was like...”What is this sorcery?”. I had no clue what I was looking at. The prep course for that exam didn’t go too far with electronics, diodes etc. Transistors, explained by this tutor, were the perfect gateway for me to go beyond timer relays and basic sensor knowledge.

    14:28 purpose of transistor: use a small current @base to control a larger current
    NOTE: current is directly proportional to voltage. so, small current means small voltage (0.6V> @base)
    16:00 how to get a small current flow?
    FACT: most LED can only handle about 20-30 mA < burn out. Voltage drop across LED is approximately 2V

    @galalon2417 2 года назад

    Very useful. Easy to understand. Well explained.
    Be careful not to confuse BPJT npn, with MOSFET N channel.
    In an N channel enhancement MOSFET, the gate(base) voltage has to be above the drain (collector) voltage, at least by the gate treshold voltage.
    in a MOSFET the gate(base) is completely isolated/different circuit to the drain-source.
    BPJTs are obsolete. MOSFETs have superior technical performance.

    • @karolakkolo123

      BJTs aren't obsolete. You can use them for current amplification. You can't do that with MOSFETs because they are voltage-controlled

    Gerat video. I'd like to comment on the saturation region of operation mentioned at 16:54 and 28:29. Rc must be large enough and Vc must be low enough so that Vb > Vc, and the base - collector PN junction for this NPN transistor becomes foward biased. So, in my mind, saturation is not just any old Vcc / Rc or just the max current of the circuit. It's Vcc / Rc if (and only if) Vb > Vc. In other words, the base-collector junction must be forward biased to have the transistor operate in the saturation region.

    I agree with most everything he says except the way current flows. It was instructed to me that current flows from negative to positive in a DC circuit.

    • @RBgamesbr
      @RBgamesbr 3 года назад +2

      That is the flow of electrons, since they hsve a negative charge, they flow from the negative to the positive. When talking about current, it is conventioned that the flow is from the positive to the negative sides. Most formulas and rules apply to the current flowing the way its conventioned, so I suggest sticking to it when doing your own calculations to avoid unecessary mistakes.

    • @karhukivi
      @karhukivi 3 года назад

      @@RBgamesbr Agreed! Most electronics technicians and design engineers pass their entire working lives using conventional flow and it doesn't make a blind bit of difference. As a physicist, I only need electron flow when dealing with electrochemistry, magnetic fields or gas discharge tubes, x-ray tubes, thermionic valves etc., otherwise conventional flow is just fine for circuit diagrams and totally irrelevant for AC circuits.

    Really admire your presentation;however, when Q1 Base is high enough to essentially close the Collector Emitter channel, or close the switch, the Vce or potential between the Collector & Emitter is effectively 0 Volts (or .6V) not 7.49V as presented. Vce would be 7.49V in an inactive transistor state (or open switch if you will). Thank You Again!

    • @brownmonkeybananayellow
      @brownmonkeybananayellow 3 года назад +3

      Are you referring to the section around 23.03? Should he have called 7.49V Vc rather than Vce? Or is that the same and should be .6V?
      Thanks trying to make sense of this

    • @ceredril
      @ceredril 2 года назад +2

      That is incorrect i think. Since the Transistor is operating in forward active mode, V_CE is actively blocking some current from flowing through it. This results in a potential difference btween C and E. The 7.49 Volts are correct.
