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)
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.
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.
