6:17 Question: Are we assuming from the start that the circuit would be connected to point A and to the point between R4 and R5 ? What happens if the circuit is assumed to be connected to other points such as point A and point B or point B and point C would we get different R equivalent for those circuits ? Thank you for your great videos.

[@MichelvanBiezen]

That circuit is known as a bridge circuit and is connected at the top and at the bottom.

[@altuber99_athlete]

Q: Why _R_1_ and _R2_ aren't in series, and _R_4_ and _R_5_ are neither? A: two components are in series if _(i)_ they both share just one (not two) common node; _(ii)_ that node that they're sharing is exclusive for them, that is, that their common node is not being shared with other components; (iii) therefore, the current through them is the same. Now, perhaps in the diagram of this video it is not shown clearly, but a wire is exiting from _(A)_, and another from the lowest node. Therefore, the pair _R_1_ and _R2_, and _R_4_ and _R_5_ aren't in series.

[@milescababaros4433]

thanks for correcting that, that had me confused

[@alexiaachthoforidou]

4:20 are R4 and R5 in series? I understand why Rb and R4 are in series and why Rc and R5 are in series, but i can not understand why R4 and R5 in series? Thank you so much

[@4junglejim2]

Thanks ,very detailed and easily explained.Now that I know the total current how do i find the individual currents in the circuit.Did this using kirrchoffs law when i first got into electronics some 50 years ago, this bridge circuit has always been difficult to work on -to many equations-.

[@adzplus1]

Great video master. I wish my professor would explain like you and with an American accent

[@IDKISTILLDK]

Bless you, good sir. I love your explanation. THANK YOUUUUU!!

[@swimcoach3702]

I notice that by removing the top set of resistors we effectively eliminate the cross resistor R3. But I wonder what if we had removed the bottom set of resistors having different values from the top? We would still eliminate the cross resistor, but should have different values for the survivors. Could you do another video showing that using both methods we obtain the same result?

[@MichelvanBiezen]

There is only one method (that I know of) to perform a delta to Y conversion. This is derived by using Kirchhoff's voltage loops and current nodes.

[@amjadalilaskir6626]

Thank you sir ,you save my time

[@Suly.m005]

Hi teacher, I have a question . Is there any general relation of current or voltage between delta and it's corresponding Y circuit ?

[@MichelvanBiezen]

They are equivalent in all respects of resistance, current and voltage.

[@MichelvanBiezen]

For the lower part, it is not necessary.

[@thetidalflow3069]

Thank you, sir, for doing this easy. I am from Bangladesh.

[@MichelvanBiezen]

You are most welcome.

[@appahoopjack2514]

So, Rb = R1... Rc = R2... Ra = R3??? I'm asking because after you made the conversion, then re-drew the schematic below, it is important to know which resistors are in relation to the other side of the circuit where the other 2 resistors were NOT involved in the Delta-Wye Conversion. In other words, how did you determine that Rb is in Series w/R4 & Rc is in Series w/R5? If someone does NOT fully understand, then the calculation may be performed INcorrectly

[@MichelvanBiezen]

This video shows how the resistors are converted: Electrical Engineering: Basic Laws (29 of 31) Delta to Y Conversion Derived R1=? as well as the 2 following that one.

yes, we typically use Kirchhoff's rules. I remember doing such an example but can't remember where.

[@alexiaachthoforidou]

@@MichelvanBiezen thank you for your reply! but why? I am a little bit confused about the current! I thought that r4 and r5 have the same current and that's why are in series..but you told me that are NOT. I don't understand how to think to find the right type of connection...What can I do? Thank you

[@MichelvanBiezen]

The current through R4 is not the same as the current through R5

[@salma11997]

thanks for making it that simple!!

is it the way i press my calculator...but its like am getting a different answer everytime i use the lower circuit instead....anyway..let me stay calm and try to figure it out...but i will be glad if am corrected instantly

[@MichelvanBiezen]

Depending on which calculator you use, the order of your operation is important. Try to calculate each part separately and see if that works.

Sir, if I instead transformed the bottom side as the Y connection, is that still correct? I got exactly 6 as the answer though, I used fractions so I didn't round off any decimal

Yes, you can do that as well and you will get the same answer.

[@aram5642]

Not sure I understand this reasoning about parallel and serial connection. To me, Rb, Rc, R4 and R5 are all in series. R4 and R5 share a single node, just as Rc does with R5. So where is the difference?

[@MichelvanBiezen]

With a delta connection you cannot use that logic. See this playlist: ELECTRICAL ENGINEERING 2.1 BASIC LAWS SUPPLEMENT
