AC Theory: How to Calculate Power Factor in an AC Circuit: What is Power Factor?

Edit: at 11:44 I should say "A capacitor produces CAPACITIVE reactance." my apologies for any confusion.

In this video I explain how to calculate power factor in an AC circuit and answer the question: What is power factor? I build on information covered in previous videos and tie it all together to explain how power factor is shot through every bit of AC theory covered so far including, inductive loads, lagging circuits, impedance triangles, power triangles and phase angles.

If you'd like to buy me a refreshing beverage to say thank you please click the following link, don't worry if not though, no hard feelings!

FINALLY, a video that explains it all using ONE right-angled triangle, that in fact, each in the three is (effectively) the same animal.
cos θ (or ϕ for phase angle), ° = Adjacent/Hypotenuse = VR/VT = R/Z = W/VA = Power Factor.
Where θ (or ϕ for phase angle) = 0°, VL = 0, X = 0, VAr = 0. This is a DC (direct current) circuit.
Thank you for the best clarity that I have seen to date!

I would like to thank you Joe for all your series of video uploaded and I spent my last 10 days going through them in order to be ready for my Adv Sc Princ L3 at Optima London Training Centre, I have smashed it. Thank you Thank you Joe. you don't know how many of out there who are taking advantage of your video. May God continue to give the courage, and enough energy upon years coming Joe.

Finally a video that deals with this topic in a simple but complete and in-depth way! Thanks for all your phenomenal videos that deserve a thumbs up.

Your videos are very much appreciated. I’ve been struggling with A/C theory in my power engineering for weeks. Trying to wrap my head around everything. Your videos laid it out perfectly and it makes perfect sense. Thanks man, this will go a long way in helping me pass my test next week.

[zacharybob]

Sure appreciate your efforts in these videos Joe, makes a world of difference to supplement my Electrician apprenticeship coursework with your teachings.

[mahmoudalphysics]

I am so sorry that I don't know such a proper way to thank you for your impressive work, please keep going

[Antiquity_Zine]

Very informative. I’ve learned more from this short video than the past few weeks from my instructor. Crunching numbers doesn’t always add up.

Hey wonderful joe I wz really fearing this subject I wz hoplessly thinking I wz gonna get lost but listening to you giving me a great hope .Im a 68 yr old trying to get my head around this for my Electrical theory level 3 nite class.Thank you so much I can do this now wth comparative ease yahooee

[ranjan]

Awesome, you make things so simple. Looking forward to your next video on the sizing of the Capacitor needed to improve from low Pf also the required KVAR.

considering i ve been a spark for 30 years, still a good sunday morning watch, never stop learning . good video

[eddieking]

Clear explanation, your videos are top notch, thank you.

[mitchellshallcross]

Great timing, currently going over this at college. Great video for continuing my development. Thanks
Wanting top mark in the end of yer exam ha

[sooslikas]

this video is the holly grail of your ac theory thalmud bro! I feel enlightened and calm like a bhuudahh before my exam! Feelin' like ZEUS allready! ( he was the first sparky ever, innit)

[kilyobasbinga]

By the way, I really appreciate your excellent video presentation

[sahilyo]

this video made things so easy for me. really simple

[ianclark]

Fantastic video as always Joe. It's great to see new ways of delivering a sometimes difficult and confusing subject to present. I find myself talking back to you which the wife finds quite amusing. Keep up the good work

[Javier-up]

Sir, thank you for this lesson. It's helped me a lot.

[munafmufc]

Joe...you should be given a knighthood for all your helpful videos. They are very clear and concise. So helpful for apprentice and students like me. Thank you.

[edsherwood]

I’m going through AC theory now and man I wish I had you as a teacher. Thanks for the videos you got a new subscriber, keep them coming

[jadenjosea]

thank you for all these videos, you explain them so well and make it easy for us.Thanks alot keep on giving these lessons
