I don't know why I haven't said it sooner but THANK YOU! Your videos have helped me immensely so many times in the last 2 years. I don't want to bash any of my teachers but some are not easy for me to follow. You are so incredibly clear and concise. The part that you added at the end (about power consumption) really helped me wrap my head around how zeners work.

My Major was Electronic Instrumentation some thirty years ago and I learned this among many other things. What I had forgotten since then ....this video brought back to recall. Good job. But what I didn't realize were the currents between RS and RL would be different during its op; somehow that just doesn't seem right. When the Zener falls (drops) out RS & RL current is the same....am I not correct?

Great video, really informative, but you have a mistake when calculating efficiency. With Rs = 1k and RL = 747 ohms, Rs dissipates 15.92 Watts, while the RL dissipates 12 Watts. While it is true that your Zener diode did not lose any power, your overall efficiency is just 43%, since the load only consumed 43% of the total power into the system.
@SaturnAR2 жыл бұрын
I'm sorry but you're also wrong. P=VxI PRs=VRs x IRs= 15.92V x 0.01592A= 0.2534W. PRl= VRl x IRl= 12V x 0.01592A= 0.191W. Circuit total consumption is: V x I = 27.92 x 0.01592A = 0.444W from witch 0.2534W is lost at voltage regulation resistor; so circuit efficiency is 43%, yes.

@alexandersolon65483 жыл бұрын
Sir, I have a question on 16:02 you said that as the "R(load) Increased it began to draw more current from the ckt, and theres less avalable current to flow from the zener diode." shouldn't it be as the Rl decreased, it will draw more current since it would take the path of least resistance.
@vashtalelq3 жыл бұрын
You are correct, when you say the load increases you refer to the current not the resistance, so when the load increases it means that it draws more current, so Rl should be less, Rl is refered to as the load resistance.

Check the last comment about using the higher RL value to choose an ideal Rs. If the RL drops, the zener will stop regulating. Otherwise, great video.
@j0mell02 жыл бұрын
@ 28:16 this assumes that the breakdown voltage of the zener diode is exactly at 0mA for regulation , which is not true in reality since there has to be some leakage current and minimum current(I min) to "turn on" the zener diode as a regulator. Therefore at 0mA, it's a voltage divider circuit that's regulating 12V, so the actual % efficiency is really the heat dissipated from Rs relative to the heat dissipated from RL(assuming heat from RL is for useful work to external load). P(Rs) = I^2 * Rs P(RL) = I^2 * RL % efficiency = RL/Rs ≈ 75% efficiency

But the line resistance ranges(50 to 1000ohms). What rated TVS can run along with the inductive load which operates at a minimum voltage of 19volts ?

How can the output voltage stay the same? Wouldn't it just bypass the z diode? Is a diode acting as a traffic stopper? Like the speed limit is 10mph(voltage) for z diode and even if the output voltage was supposed to be the voltage of the battery the electrones cannot pass through the wire with higher speed, because diode 10mph speed slows them down?

thanks for very informing video. how did you get the Vout of (12..05 or 12.03)v. .
@matematikadanfisikaterapan13444 ай бұрын
In the real world Volt and ampere of R-load is Fix, and Zd is have impedance (For 12 Volt, Impedace = +/- 5 Ohm), and Zd have tolerance to accept i, as max power allowed ( for this, +/ - 0.25 watt), P = (id²).z., thus id not must be zero ampere. Hence the variable that must be arranged is Vs (batteray), and Rs can random fixed as product suggested. When Vs is also must be fixed than we can use comparing- op amp and bjt (or even mosfed) beside diode Zener.

Pretty good. Last point on design was ass backwards as you would want to design for the lower load resistance which will draw more than a higher one but no big deal. I despise whole number names being used to describe decimal values though. 12.15 is NOT twelve point fifteen. It's twelve point one five. Still. Decent video.

@hadisalimi84784 жыл бұрын
If the (Rs) resistor's power consumption it taken account the output power percentage would be roughly 16%. it's so inefficient. Also I figured out that the internal resistor of the source is about 290 ohms which again has decreased the output power. (on 26':26")
