Superb video sir. Although the maths went over my head, that’s because I need to learn more. In terms of understanding the flow of things, this is a brilliant video thank you. Keep up the good work
For the negative half cycle Vo = - Vi not as he explained in the video, since the output voltage should be in both cycles positive and being Vo = -Vi in the negative part makes sense ! Since the input will be negative and the negative from the rule will make the output voltage positive ...

In the negative half cycle the phase difference of input and output is 180 degree... But it was not cleared in your lecture... To get it is needed to gain VO=-Vin.... But you get VO=Vin...
May I ask a question? I'm always having this simple question : In AC circuit we say the polarity is constantly changing. If this is true , why we always get the hot wire on only one cable when using a test pencil ? Thank you
when you hold the tester, you are connected to the ground, the resistance in your body is high enough than earth, so you don't get shocked and the circuit is complete. try holding the tester in a way the the metallic pin at the end doesn't touch your body, you won't get any hot wire, or light.
why you are inconsistent with your explanation? During the -ve cycle if Vo = Vi, then the output waveform should contain the signal below the time axis because the Vi is below the time axis for -ve cycle.
In half wave rectifier examples...we substitute diode for voltage/battery (FB) and open circuit (RB)? But in full wave it's short circuit (FB) and open circuit (RB)?
Also in my understanding of a full wave rectifier is that the current flows in the same direction through the load resistor resulting in the correct movement of a motor hook up, especially when 2 filter capacitors are connected with a voltage regulator on the output.
Sir For the negative half cycle the input is below the x axis and if output equals input in the negative half cycle so why is it above the axis i.e in the positive region?
There are two current references, the conventional current from positive to negative and this is old before atom, electron and neutron detection. the second current is the electron current from negative to positive.
when the pot difference of the input current is higher then in cap then capacitor is charged and when the pot difference is lower then pot difference of capacitor then it supply residual current
The actual terminology for the rectifier diodes is also forward bios and reverse bios in terms of the measurement at the anodes and cathodes, not voltage.
At the output across the load resistor of the full wave rectifier in my understanding the positive waves will not fall below .7 volts which is the turn on voltage of the rectifier diodes. That means the output will not fall to zero.

Great video. Thank you!! I am sharing this to more friends :)
Thank you very much, your lecture is perfectly clear!
Im lucky that i found this channel on utube
while constructing a full-wave rectifier, a student mistakenly has swapped the terminals of d3 as depicted in figure below. explain what happens
at 8:29 the graphs for all three cases will start and end at 0 and pi only, right?
Great tutorial :) Please keep posting
Please complete MOsfets jfets..

Hats Off to you man! Now I can finally understand this shitty device in physics

watching 1 day before exam
thankyou. Do you have tricky exercises on it?
Woooow your the best
please upload more fet ,etc please
why you are inconsistent with your explanation? During the -ve cycle if Vo = Vi, then the output waveform should contain the signal below the time axis because the Vi is below the time axis for -ve cycle.
Its true the second half output wave should be down the axis but he didnt give clarity
The current through the resistor is in the same direction for both the cases. Hence the positive cycles in the output.
Better than college lectures.
In half wave rectifier examples...we substitute diode for voltage/battery (FB) and open circuit (RB)?
But in full wave it's short circuit (FB) and open circuit (RB)?
Both are correct....
Is it possible to keep all the negative polarity after AC is rectified to DC ?
Your query is not clear....
Nice video
What is Ripple factor?
Please can I know what you change the sign of the bridge terminal for the analyse of the negative ac wave?
did you know the answer? if yes explain it to me please.
great

Hi. I'd like to make a *FULL BRIDGE RECTIFIER!!!*
Ok. We will make a tutorial for you.
*Get your FULL BRIDGE RECTIFIER shirts now!*
Also in my understanding of a full wave rectifier is that the current flows in the same direction through the load resistor resulting in the correct movement of a motor hook up, especially when 2 filter capacitors are connected with a voltage regulator on the output.
Sir
For the negative half cycle the input is below the x axis and if output equals input in the negative half cycle so why is it above the axis i.e in the positive region?
thank you
Shouldn't the arrow be from negative to positive since current flow is the movement of electrons and electrons flow from negative to positive ?
mutum arnica current flows opposite to the movement of electrons.
There are two current references, the conventional current from positive to negative and this is old before atom, electron and neutron detection. the second current is the electron current from negative to positive.
Hello, direction of current is opposite to the flow of electrons...
why is Vo -ve? in -ve cycle
Can you make your query more clear?
Why the D1 is reversed biased
Can You make a video on how the capacitor works to smoothen the output of this circuit?
(This video was really helpful by the way)
study filters, that will cover what you need.
when the pot difference of the input current is higher then in cap then capacitor is charged and when the pot difference is lower then pot difference of capacitor then it supply residual current
Thank sir, i have a question. Can you kindly explain sir what is the main advantage of bridge over center tapped? Thank sir from india
For center tapped, the secondary winding is double the size of secondary of transformer in a bridge rectfier
Center tapped rectifier is expensive and bulky bcoz it uses center tapped transformer
in case of negative half cycle, V out== minus(V in), you did wrong in KVC.But output waveform you have drawn correct
The actual terminology for the rectifier diodes is also forward bios and reverse bios in terms of the measurement at the anodes and cathodes, not voltage.
thank you so much
what will e the efficiency if a resistor is connected with every diode?
Output voltage falls, so efficiency falls....
how is diode D3, .. (FB)?
At the output across the load resistor of the full wave rectifier in my understanding the positive waves will not fall below .7 volts which is the turn on voltage of the rectifier diodes. That means the output will not fall to zero.
This is true only for a rectifier with a capacitor filter. For rectifier without filter, output becomes zero at the start of every half cycle.
Thank You Sir
Whats your age ?
Pls explain the capacitor portion in detail, why it gets smoothen ?
Capacitor retains the max voltage and discharges slowly, so the output become more smoother compared to a rectifier without filter...
Thank u 💞
thanks
chalak...
Tq sir
why output of both cycles comes in only positive half cycle
because of the polarity of diodes...
Through load resistor, current flows only in one direction during positive and negative half cycles
