How to Solve the Diode Circuits (Explained with Examples)

In this video, different methods for solving the diode circuits have been discussed.

There are two methods for solving/ analyzing the diode circuits.
1) Graphical Method
2) Diode Approximation

Both methods have been discussed in the video and using the diode approximation method, different circuit problems have been solved.

The timestamps for the different topics covered in the video:

1:02 Graphical Method (Using the Load Line)

3:19 Diode Approximations

4:29 How to Solve a circuit problem using diode approximation

7:46 Example 1 ( Series connection of Diode)

9:54 Example 2

12:11 Example 3 (Parallel Connection of Diode)

13:41 Example 4 (Parallel Connection of Diode with different diodes (Si and Ge))

16:11 Example 5 (Parallel connection of diode with different voltages)

Graphical Method:
In graphical method, the load line is drawn on the V-I curve of the diode.
The load line gives the possible values of voltage and current of the diode for the given circuit. The intersection of the V-I curve of the diode and the load line gives the operating voltage and current of the diode.

Diode Approximation:
In the diode approximation, the diode is replaced by the equivalent circuit. Although the values of voltage and current of the diode by this method is not exact, using the diode approximation the circuits can be solved/ analyzed very easily.

Thank you indian guy, you're saving a student for doing this tutorial video

[johangustafsson]

For every course I cannot understand, I can rest assured that there's and indian guy with a dedicated youtube channel for it somewhere.

[ahsanhabib]

I study in one of the top university in Bangladesh having one of the best physics teachers in South Asia. I admit you make it clearer than those over learned professors. Thank you so much sir.

[danielstoy]

This is the most perfect video ever. Clear and concise with perfect explanations. Thank you!

[yasminekudjoe]

I was so confused with this diodes stuff but you saved my llife. Thank you, you are the best

[harshalshah]

Before that video I was very much confused about diode solving but now I got confidence in this topic .Thanks sir for this amazing tutorial ✌️👍👍

[pranavipranu]

9:49
Current = 4 mA
Voltage = 4 volt

[SSRReloaded]

Thanks a lot, sir, my electronics exam is just 3 days away, and despite covering the syllabus, I was just blanked out of how to solve problems. Thanks a lot for making my concept clearer & helpin me on solving problems ❤️🙏

[kesusd]

The voltage across the 1k ohm resistor is 4 V and the current for the circuit is 4 mA for the example with one silicon diode and one germanium diode.

[mnada]

This is a great channel for studying circuits and electronics

[LousyPainter]

I can see an immediate use for the last circuit. Thanks. Excellent demonstration!

[akshatpanda]

Problem in 9:50 :-

current = 4 mA
voltage across Si diode = 0.7 V
voltage across Ge diode = 0.3 V
voltage across Load resistance = 4 V

[vanhoangtran]

The video is excellent with the clear explication ! Congratulation ! For me, I just have one question in the final example. In effect, what is the value of V0 if the first source is 3.5 V in stead of 2 V ? And the voltage of the first diode is 0.2 V in this case ? Thanks very much for your contribution !🎉🎉🎉

[minepro]

Again you proved better than my professor.

[salmansabbir]

Thank's Sir. It's the best tutorial. After watching this tutorial, nobody else has any problem, I think.

[jhoanasuelo]

For item 9:38 the value of I= 4mA and Vo= 4V

[shashanks]

the professor might be iitian or overlearned
the thing which matters is "THE TEACHING STYLE" in which this guy is overlearned
hatsoff !!!

[suniltiwari]

Sir, in example 5 you said that upper diode will off but for diode to be off potential drop across diode should be less than diode voltage but when you say that at right terminal of upper diode potential is 3.3volt then for upper diode potential drop is 1.3 volt which is more than that zener voltage then how it can be off ? please tell sir

[chiraggupta]

best explanation I have ever seen.... Thank you Sir for making video like this....
