Example of Y-Source attached to Delta Load

[@shawnscientifica6689]

These are amazing and the professors voice is relaxing to me for some reason haha, much easier to understand than my professors

[@filchaneco506]

to find the IbB. you could just use the same way like you did in IaA.

[@abromchris7670]

Sir ,in 16:15,there are two unknown values ,one is zita ,the other is V sub m (Some Maximum value ,but I don't know why it called Vm instead of anohter variable cuz Vm had been used in another chapter , in AC signal(Peak Value))

[@sohamkhisa1831]

Sir, how will you solve these last three equations? I mean these are unsolvable, no valid result comes out of this. Your are not going to get any of these three unknown currents through these equations.

[@HaiderAli-nm1oh]

so true

[@sa0o923]

Actually there are 2 unknowns. Theta and Vm Currents inside delta are shifted 120. They aren't entirely unknown. You just need to solve for Vm and theta

[@danielgmilne6280]

At about 7:40, did you divide by 3 because there are 3 “loads” or it that just general?

[@BalkanManic]

He's finding the parallel equivalent of the 3, I believe.

[@malganis3847]

Late reply , it's because all three sides have equal values .. so as long as that's the case , you can apply the formula that he used

[@Quran_memorization]

when u want to turn delta load into star load u should divide by 3

[@markmeii2109]

you should still use the standard formula for transforming delta to wye, it's just that the load is balanced so you can apply dividing it by 3

very good explanantion, thank you
