Your awesome! Good graphics and explain it slow enough to understand what’s happening with good calculations. You remind viewers that conventional flow is being used and what Electron flow is. Thank you
Am I the only one who finds it funny when I hear those calculator sounds when he's inputting those values every time? I find it cute LOL XD Anwyays I love this guy helped me a lot!
In the question 120 Vac is Rms value, so when we multiply it with root 2 we get peek value not the Vdc value. In order to find Vdc=Vavarage we have to divide Vpeak value to pi, which is equal do Vdc value.
No, RMS is the average already. By definition: square root of the average value, squared. 1v RMS AC into a fixed resistance will heat the resistance precisely the same amount as 1v DC will (I believe this has been used in high end bench multimeters to measure AC waveform of any shape). Average of 120v fixed DC = 120v, so the average of AC 120v RMS must equal 120v too. Edit: I may have misunderstood you…
On the center tap transformer , if I am not mistaken in a full wave rectifier the waveform is 180 degrees out of phase , which means the D1 and D2 turn on , on both positive swings of the sinewave resulting in 2 positive halves on the output.
Because the waveforms are 180 degrees out of phase we can have a hot and neutral line or return which is 180 degrees out of phase. That means the relationship between a V.O.M which measures peak to peak value is measuring in digital form or analog form from HOT line to NEUTRAL or Black line to white line we can so measure 120 VAC in phase, proved on an oscilloscope we will measure peak to peak value in phase as 60 +VP to 60 -VP right in phase. That relationship of the sinewave is on one line and to the return in a circuit. That shows the phase loop.
I have a center tap transformer it was for microtek ups 1400. I want to use it for for battery charging and I don't want to disturb its design. The challenge is that the center is positive I wonder how the diagram of electifire should be away from the this one you have just explained.
Love the video, it helps a lot. But 1 quick clarification: You said the peak voltage is 12*sqrt(2) = 16.97, but when calculating average voltage you use 16.27 (16.7 - 0.7) as the peak voltage. What is the new value (16.27)?
@@nurhafizahaziz6785 We use the 16.97 V if we are solving wuth the "Ideal diode model" which ignores the parrier potential of the diode (0.7 V in silicon diodes). But the correct way, or most common way is to replace the diode with a 0.7 V battery then adding or subtracting it from the original Vp.
What is the point of having a center tap transformer? I understand that the bridge rectifier allows for the full secondary voltage at the output vs this type of full-wave rectifier which reduces it to half, but I still cant figure out the purpose of dropping half the voltage before it reaches the output. Thanks for the videos.
I think that in a way, you don't necessarily "drop" more of the voltage with a (non-bridge) full-wave rectifier compared to a half-wave rectifier. In a half-wave rectifier, you can think of it as going from V = 0 to V = Vpeak, while in a directly center-tapped full-wave rectifier, you'd go from V = -Vpeak/2 to V = +Vpeak/2. The range is still the same (Vpeak, or the max voltage across the entire secondary coil), but instead of larger half-waves, you get smaller half-waves twice as frequently.
@@chrisreale4326 I’m glad my explanation could help! A lot of times I try to reply to things to lock in my understanding. I also find it interesting to reply to very old comments, to see how people have been doing and to start up some conversations.
@@PunmasterSTP sadly I forgot most of the stuff I learned in that solid state electronics class already, as well as electrical theory in general :( But I will say when you graduate don’t hesitate to apply for anything and everything that seems even mildly interesting!

I think if you need to make DC current (such as for electronic circuits) but you start off with an AC current source (like the electricity from wall outlets).
@@ThomasACarlos Hmmm…if you have access to a simulation tool, it might be worthwhile to double-check using that. What components were you using? (i.e. load resistor, diodes, transformer, AC source, etc.)
@@ThomasACarlos Oh it's quite alright, I was just curious. I like to reply to old comments just to see how people have been doing, and start some interesting conversations. How has school been going/how did it go?
Hi Good Sir what if the other diode is forward biased and the other is reversed? then the two diode will be turned on in positive and on the negative will be both turn off. how can it be solve that way? or is it even possible to solve?
I stopped watching 7 mins in, the explanation of the full wave rectifier with a center tapped transformer was way wrong You also need 4 diodes to make any kind of dc rectifier and that's not even getting to the missing capacitors and resistors to make this work

Thank you . Finally i can understand that
you explain int the best possible way
great video thank you 🙏
Thus vid really helped me with a course I'm on. Thanks 🙂
you have to divide the peak voltage by 2, as it is center tap.
Amazing information and insights; thank you so much for making and sharing these (non-ochem) videos!
Always the best 💃💃
Great tutorial

a very helpful video! thanks...
So great. Easy to understand. Thank you

First I'd like to give a great appreciation thanks alot. And I wana you to make tutorial on Small Ac signal MOSFET JFET pls if u can
Better than best!!!
excellent video
subbed, good video
Brilliant!
MY TEACHER IS SO BAD, THANK YOU
How is Vp 120VAC? that the RMS value correct? should 120 be multiplied by 1.414 for Vpin?
Thank you very much
well explained
To my understanding also in electricity there has to be a load to draw current to it.

up
That's the output voltage. Vo,pk = Vs,pk - Vdiode = 16.97 - 0.7 = 16.27
peak voltage the resistor will deal with.
ya, quite confusing when calculating Vaverage you use (16.27).. y dont you use (16.97) instead? anyone explain please

I'd like to see this proved in a lab. I am getting close to 15.5 vdc on the output. What value resistor are you using? Thanks.

THANKS
What about when both diodes are flipped to reverse Bias, I have a practice problem like that and Im so confused how it isn't an Open Circuit
Nice
what must be the value of the resistor?
You need to know the is current this video for exp the full wave rectifier
Vr = 16.27 v
The transformation prob
Its given is or ip current
thank you
Think you
So why doesn't a center tap short circuit the inductor?
good videos friends
Good
that's cool but help us to see step by step how to measure it
Wow 😲❤️
Your invited to my graduation!😂
*You’re

thats good men
Your diodes are backwards. Your diagram shows the center tap as being always negative.
