Y parameters- solved problems
_______________________________________________________________________________
Hello friends,
Welcome to our KZfaq channel Electronics for You. This channel is all about Electronics Engineering and its allied branches. We even upload some videos which are basically well known Engineering terms but people don't know much in details about them.
________________________________________________________________________________
About this video:
Note: if you dont have basic knowledge of network analysis please watch all videos in sequence as that of this playlist.
In this video, one problem of Y parameters is solved. Here this is solved by using mesh analysis and assuming supply voltage as 1V. In Y parameters one port is short circuited at a time. If you are not getting what is taught here please see video • Y- parameters | Short ... and mesh analysis numerical first.

When port 2 is short circuited opposite resistance 6ohm became 0. In that case when port 1 is short circuited opposite resistance 4 should become 0.

@ElectronicsforYoututorials 3 жыл бұрын

At port 1, 2 ohm resistance is in series with source hence 4 ohm resistance can not be short circuited.

Sir,I want to asking that it is possible for us to solve this problem without using mesh analysis? Because my lecturer didn't teach me using mesh analysis method and I worry they won't accept this method especially for our assignment and Exam.I really appreciate if you can make a video about this problem without using mesh analysis.

Sir why 6ohm is also shorted here???

@ElectronicsforYoututorials 4 жыл бұрын

Its because in Y parameters we have to short circuit one port at a time. If you short circuit output port then definitely no current will flow through 6 ohm resistor. Here, "current always follows the less resistance path" rule is followed. In short, we have not shorted 6 ohm resistor but have removed it bacause no current flows thrrough it. Reply if you have any query.

Sir if there are three loops in a circuit means there is an other resistor parallel to 6 ohm and he said to find y11 and y12 so how can we solved

@ElectronicsforYoututorials 4 жыл бұрын

If there is another 6 ohm parallel resistor to last then you can solve for parallel resistance combination. But if you are asking about again one more loop then go for 3 loop kvl/mesh analysis and follow same procedure. This video will help you. Only problem is that, It is in Hindi/urdu. But i hope u wl get it. kzfaq.info/get/bejne/jrJ3eZCbrrW-moU.html

Sir but with out given the voltage how can we assume V1 as 1volt

@ElectronicsforYoututorials 2 жыл бұрын

In math we assume several variables and many motr things... Similarly we can assume here also. In network analysis, we assume direction of current similar concept can be used here to simplify. This method simplifies the problem hence we assumed voltage source of 1v.

@g4_varunjain794 Жыл бұрын

I think the direction you assumed initially in the port 2 is wrong please check once

@ElectronicsforYoututorials Жыл бұрын

Technically you are correct but its only assumption. Therefore, you can assume any direction of current. Only change will be polarity of current (may get negative).

hello sir, I have a doubt. When V1 = 0 why isnt the 4ohm resistor shorted?

@ElectronicsforYoututorials Жыл бұрын

Because 20 ohm reaiatance was in series. Hence 40 ohm was not actually shorted.

Resistance is shorted (hence removed) only when it is parallel to the wire in second case ot is in series.

@laurewako9892 3 жыл бұрын

When port 2 is short circuited why is 6 ohm resistor also short circuit

@ElectronicsforYoututorials 3 жыл бұрын

Because current always choses low resistance path. As short circuit has zero resistance whole current will pass through that branch and not through 6 ohm hence it will also short circuit.

The system of equations can be solved by two methods. 1. If engineering calculators are allowed then use equation mode of calci and solve. 2. If calci is not allowed then you can use matrix method for solution.

@ElectronicsforYoututorials 8 ай бұрын

The Y,Z or H parameters do not depend on applied voltage hence the action of input voltage can be neglected. You can assume any voltage for solution. this method is simplifying the problem.

I1 and I2 were mentioned in problem. The direction of I1 and assumed current was same but in case of I2 and assumed current the directions are different so instead of calling it I2, it is called I3.
