I completed Circuit Analysis last semester at community college and am now at a four-year college taking EEE 117 (Network Analysis). I wish I had watched all your videos on electrical engineering last semester, but they are still helping me tremendously! Thank you so incredibly much for taking the time to post such awesome videos! I also used your physics videos quite extensively. I thank you eternally!

You are awesome!!! I recently finished my Physics for Engineers class (the thermodynamics, optics and fluid part) in December and I utilized all of your videos from your sections related to those topics and scored an A on my class. I am now scheduled to take my first Electrical Engineering circuits class in January and I am getting head start by watching your entire video list on EE...I know I will be sitting pretty by the time class starts and all due to your superior teaching skills!! Thanks so much!!

How come at the end the right part of the parallel circuit sums up to 30.133? I thought that since one of them is 1.33 and the other one is 30 and they are in series, the total resistance of that branch should have been 31.33.

Is it necessary to deactivate the voltage/current source while applying Delta-Wye conversion in a certain section of a circuit? An answer to this question would be very helpful as I have an assignment related to this topic that needs to be submitted some days later.

@MichelvanBiezen

2 ай бұрын

The delta - Y conversion is independent of the voltage or current source. It only affects the resistors. Not sure what you mean by "disconnect". If I understand you correctly it would not be necessary, but then I am not sure about the situation you are referring to.

@TheProGamer-ey7sy

@@MichelvanBiezen it's ok, I got my answer, thank you so much. One of my friends told me that while using the Delta Wye conversion, I need to imagine the circuit without any current/voltage source and perform the calculation, and then later on (after finishing the calculation) put the sources back in the circuit in their previous position. Basically, she told me that I can't perform Delta Wye conversion in a circuit if it has any kind of current/voltage source. I just needed to clarify that confusion, and you did it nicely. Thanks again.

how can you calculate the current that runs through for example 20 ohm resistor?

@MichelvanBiezen

6 жыл бұрын

First you need the voltage drop V (on 20 ohm) = 10V (12.97 / (10 + 5.333)) Then you want to find the current: I (through 20 ohm) = I total x (31.333 / (22.133 + 31.333)

@MichelvanBiezen

You must calculate the voltage at each end of the 4 ohm resistor. There are several circuit solving techniques that can be used. Kirchhoff's rules are a good place to start. I believe we made a video that shows how to do that.

A delta circuit contains a bridge between the 2 nodes of 2 sets of 2 resistors in parallel.

I was taught a more complex equation for delta to y conversion but Dr. van Biezen's equation helped me solve a problem for ELE 211 DC circuits. I used the equations taught in this video and solved the equations for the problem in my course. If anyone has an insight in the differences in the equations and how to apply them, please respond to my remarks.

@@MichelvanBiezen I was shown RA = (R1R2 + R2R3 + R1R3)/R3, RA = sum/R1, RC = sum/R2. I was solving a Wheatstone bridge problem with resistor load instead of a galvanometer between the two series resistors. I solved the lower half of the circuit using a delta conversion. my solution worked in Multisim. The second part of the problem asked to solve the upper half using a Y conversion. Your equations gave resistance equivalents that equaled the circuit measurements.

They are probably the same equation in different form. Did you try to convert one to the otther.

Can you explain why you used the top portion to convert to a Y circuit?. It's just I get the same answer as you doing it this way, but if you convert the bottom portion of the delta to a Y circuit you get a R(eq) of 10 ohms less.

The 4 ohm resistor is eliminated by doing a delta to Y conversion. However if you still wnat to find the current in the 4 ohm resistor, you will have to use the Kirchhoff's technique on all the loops in the circuit

any chance that you can direct me to a y to delta conversion? I don't think you have one.
