In this video, the resistance of the diode has been explained.
The following topics have been discussed in this video.
1:52 DC or Static Resistance of the Diode
4:49 AC or Dynamic Resistance of the Diode
6:47 Derivation of the dynamic resistance
10:22 The average AC resistance of the diode
12:42 Summary
When the diode is conducting then it offers some finite resistance and the resistance offered by the diode depends on the type of input signal (AC or DC Signal)
DC or Static Resistance of the Diode:
When the DC voltage is applied to the diode, then the resistance that is offered by the diode is known as the DC or static resistance.
When the diode is forward biased then the resistance offered by the diode is known as the Forward DC Resistance and in the reversed bias condition it is known as the Reverse DC Resistance.
AC or Dynamic Resistance:
When the AC signal is applied to the diode then the resistance offered by the diode is known as the AC or dynamic resistance.
Average AC Resistance:
When the applied AC signal has very large voltage swing then the resistance of the diode is known as the Average AC Resistance.
This video will be helpful to everyone in understanding the diode resistance.

Thanks sir🙏

@neethueldhose1330 3 года назад

Which resistance is greater ? Static or dynamic resistance

@ayoungmuslim8223 2 года назад

Thanku sir for the amazing series I am preparing for neet 2022

Dude this is engineering 1st sem syllabus 😭

@kothapallysandeep587 6 лет назад

Good explanation.

@theguitarist5547 2 года назад

The slope in that graph will be change in y(current)÷change in x(voltage) thus, shouldn't it be 1/R or resisitivity?

@pratikas2589 2 года назад

He did say inverse of slope

@vanhoangtran8783 Год назад

I just have a question at the total resistance. You said that this resistance = DC/AC resistance + bulk resistance, but when I asked chat GPT that it isn't equal (it explain : "The term "bulk resistance" is not commonly used when referring to diodes. However, diodes do have a parameter called "dynamic resistance" or "differential resistance," which is a measure of how the diode's voltage-current characteristics change around a particular operating point... In general, the total resistance of a diode is not equal to the sum of the bulk resistance and dynamic resistance..." I don't know which answer is correct. So I ask you to verify this question. Thanks very much !

@sampadkumarmishra4346 3 года назад

sir why the dc resistance of a crystal diode is less than its ac resistance....

@sushmitamahapatra4472 2 года назад

Sir please make a video on capacitance of pn junction diode🙏🙏

@harikrishna1913 6 лет назад

Hi sir.I am your best follower. sir if you don't mind can u upload concepts of diode, transistor,amplifier and multivibrators in detail for csir ugc net oriented.

@ALLABOUTELECTRONICS 6 лет назад

Yes, I am going to upload more videos on the diode. And once it is finished, I will start videos on the transistor.

@noweare1 5 лет назад

Is the total resistance Rac + Rdc ? or Rac + Rbulk or Rdc + Rbulk, got confused at the end there.

@ALLABOUTELECTRONICS 5 лет назад

Its the summation of Rac or Rdc + Rbulk. If only DC voltage is applied then one needs to consider Rdc. Similarly, if AC resistance is applied then consider Rac. So, that total resistance will be either Rac or Rdc plus Rbulk. I hope it will clear your doubt.

I want diode capacitance vidoe sir

@naveennataraj1578 4 года назад

we assume that the resistance of the diode is zero (very small), but why are we getting a huge dynamic resistance.

@ganapathisanthosh6815 4 года назад

Why forward bias characteristics of diode after threshold voltage is exponential?

@vbidawat93 2 года назад

So when the diode is subject to forward bias voltage the current start flowing exponential.. that is a fact.. and that is also evident from the diode equation.. you can see the derivation of the equation from where the exponential comes and you'll get your answer
