Parallel RLC Circuit Example Problem

So can i write impedence to be z = 1/✓((1/r)^2 + (wC-l/lw)^2) where w is the omega for the sinusodial current?

Thank you

why does no one use complex math to calculate these? add 88.42 dms 90 30.16 dms -90 plus 60 dms 0 whatever their respective currents are and then you get your It

cos Phi = R/Z or Z/R which is true?

Thank you video, please tell me how can i calculate power factor for this circuit

Thank youuuu, I'm in BEC now solving for my life. Go Marines!

Am studying solar installation at s.t john paul 11 catholic collage chilomoni Blantyre malawi , your videos are so amazing and brilliant, am very inspired and i have learn alot through your plat form I was blank in my head concerning this mathematics and I was thinking of giving up. Now am challenging that I can not fail after watching your videos


You are my hero

We appreciate thank you

What if your professor wanted everything in phasor form

Thank you ❤

Thank you ❤

You are the real mvp for taking the time to make these videos to help a 37 year old like myself fresh up on these things. thank you brotha!!

Thanks for your video😊

this crazy ass tutor teach everything but organic chemistry

thanks man

this is very helpful, but my problem is i have 2 capacitors and i assume i need to combine them? i have to plot the frequecy and current. Any tips for this please ? i would think i need to get the total for c so i can use the resonance freq formula

can anyone explain why when adding the currents, you get the wrong answer? why do you have to subtract the currents going through the capacitor and inductor?

How would this change when the 12V/60Hz source has a 50 Ohm impedance?

the best ever

Organic chemistry tutor , still saving grades with 4 years old videos ,
Legendary stuff 👏🤗 .

Legend 👏

What about series parallel RLC circuit .
Don't you have?

This video is very helpful for me because iam a student of iti as a electrician so thanx to you sir uploaded this beautiful video 🙏🙏🇮🇳

in parallel ckt net impedence is always less than the minimum among all components individual impedences. but you got 36 as net impedence when an element having 30 impedence i spresent already there answer should be less than 30.

How is the formula for resonant frequency same as that of series rlc. circuit?

Nice

I assume both equations here for Zs and Is wouldn’t work for a circuit with Resistor, dirty coils and a pure capacitor?

Why u dont use index number?

In the beginning for impedance your math is wrong at the end.

why is he not using complex numbers for the impedances? I thought the impedance was supposed to be: Z=R+jwL or Z=R+jwC?

hi sir please teach me how you type those numbers in calculator, i cant get the exact answer on the total
impedance

Your videos are amazing. I'm currently studying to become an electrician and your videos tie loose ends. Thanks!

thank you for all that you do and I really love your videos

parallel fr u lied

maybe tell us how to type it in the calc... thats literally the hardest part..

could you please also explain (or kindly point to other resources) how would we find the impedance if, say a resistance, was added in series to an LCR parallel combination, and how current would be divided.

Z=R=60Ω (ringing status)

thanks Sir

Chử quá xấu

omg wtf is going on , im soo interested want to learn but cant everytime i listen i feel so sleepy. coffee won't help, so regret sleeping in physics now that i need it all the time

thank you sir

Tq so much for this!!!😇😇 now I understood this topic ...

Thanks for making all of these wonderful videos; I really appreciate it. You’ve taught me so many things so succinctly that I’ll always think of you as a professor!

How to find the phase difference between the net current and source voltage in parallel lcr circuit....????
