Questions from Viewers: AC Theory, How to Calculate Power Factor and Draw a Power Triangle to Scale

In this video we answer another question from a viewer on how to calculate power factor and draw a power triangle to scale, this question came from a mock exam and is a typical question that comes up in electrical assessments.

This video is designed to help learners studying any electrical course especially CIty and Guilds 2365, 5357 and 8202 as well as the EAL Diploma in Electrical Installation.

The whole series makes AC Theory crystal clear, and simple to understand thank you Joe Robinson

[triplerjm]

Thank you Joe for this video and doing my L3 adv science exam on 06/09, you've explained it cleared better than my teacher, getting my understanding.

Great topic and great explanation. Thank you sir for sharing your ideas. Upload more videos. It helps a lot. Godbless.

Great video. Who ever thought maths would come in handy again, I need to go through all of your other AC Theory videos 👍

Hi Joe. Great lesson. Could you think to write your equations in a bolder larger type. You see what you've written because you are close up. Your camera doesn't see it the way you do. Some of us are visual learners (videos) which means we scan the info often for reference as you continue to discuss the subject. It would be nice to be able to scan more easily. Thanks.

Great videos. One question. Where does the true power number come from? If you are measuring volts and amps with a multimeter, doesn’t that mean that watts (true power) are going to equal apparent power?

[jclarkson]

Nicely explained thanks, so I press shift then cos👍

[ravindulakshan]

Thank you sir.. It is very helpful to us... Sir, As I think, ApparantPower * Sin(53.63) is a easy method to find out Reactive Power.

Highly appreciate your teaching method. If you don't understand this video, please go back and watch the previous video and if you don't understand that, go back to the previous :)😬

Mr joe tnk u very much for presenting this series that was very usefull backup me.i would like to make a small reqest, plz more explain capacitors..how it charj, how effect the voltage and freqency, capacitance, In connection with these things.

[sohailjanjua]

Hi Joe, Your lecture is excellent . Thanks

[vanderpant]

Great vid Joe, nice to consolidate and apply previous vids 👍

[robertoancea]

Hi, can you please explain the impedance formula as a square root of the R^2 + Inductive reactance^2 and make R as a subject? Big thanks in advance! Roberto

[tedlahm]

Joe: Wonderful video. As you explained before the power factor for Restive
load (lamps or heaters) would be 1. My question please. You mention that
this is an INDUCTIVE load, but would the PF be the same for a capacitive
load, given the same known integers? Thank you as always.

[selvamm]

Hi Joe how use to kvar rating in capacitor bank and it how reduce EB bill for industrial?
Pls explain hormonics?

[munafmufc]

You deserve a knighthood Sir Joe for the clear and consise explanation. Lol. Thanks for another great session.

[ismaelkariuki]

THANKS Jeo you helped us a lot by the way you do have the best videos say hi to the team.

[RamonFernandesB]

Hi Joe, thank you for your videos its amazing.
I have a similar question on my mock paper but the Current is 4.5 A. doesn't seems to work would you be able to help.

[jolyonwelsh]

Power factor is usually represented as a percentage, in this case it is 59.3%. This is because you can't have a power factor greater than 1.0 (unity) or 100%

Good morning Joe. Is your college still open to you? Mine is closed and I'm working from home.
