47 - Solve AC Circuits with Complex Numbers

[@sutirthjha4539]

Love your for this video. Cleared a lot of stuff for me.

[@SkanCityAcademy_SirJohn]

Thank you very much

[@SikoriyaAggrey]

How do you add up the impedences across branch A and B

[@SkanCityAcademy_SirJohn]

You add them in parallel

[@chandapathias5134]

How will I explain to my kid that this video made me answer my assignment within 30 minutes 😹😹

[@SkanCityAcademy_SirJohn]

Hehehe

[@aaronmensah726]

Why are you working in polar form?

[@SkanCityAcademy_SirJohn]

That's the easiest way to solve such a question, and notice that at the end, we will need to compare the phase of the current values with the voltage, so you'll definitely need to convert to phasor form. So why you do that in the initial stage

[@ephe8949]

I read that polar form is only easy for multiplication and division then rectangular for addition and subtraction. I was confused during the video.

[@SkanCityAcademy_SirJohn]

Yes, I get you, but once you will need to find the phase angle at the end, it's best you do the conversion first, that's the easiest way. Moreover, you are not going to solve step by step. You will need to complement your solution with a calculator

[@rafaelaguila365]

Is the result of ZT wrong? That result 19.25 makes no sense?

[@SkanCityAcademy_SirJohn]

its correct actually

Pls we want to be able to download these kind of videos for reference sake

[@SkanCityAcademy_SirJohn]

You can

Please how did you add it ??

[@SkanCityAcademy_SirJohn]

Add what please?

[@SkanCityAcademy_SirJohn]

No

@@SkanCityAcademy_SirJohn can you explain how you added the parallel impedances

[@augustusquayson3649]

Pls how do we ponch the polar on the calculator

[@SkanCityAcademy_SirJohn]

It's been a while since I used that calculator, kindly check out videos on KZbin or ask a friend to assist you. Please sorry about that

[@Westdmond]

About zc can you please double check sir

Where from the negative sign

[@SkanCityAcademy_SirJohn]

Can you please specify the exact time in the video so I check for you?

[@Westdmond]

@@SkanCityAcademy_SirJohnI guess is talking about zc ,wanna know too why is that negative

[@ephe8949]

When I calculated the angle of Zb, I got 1.413

[@SkanCityAcademy_SirJohn]

kindly recheck your calculation...
