I did my elelctical engineering technology and my elelctical apprenticeship both at NAIT. And the way you solve the problem is the most understandable for trade and EET students. And works really good and clear.

Just a reminder: This is Gold!

I explain this to electrician in Boston. Thanks for sharing a clear resource.

I did degrees in other countries. I believe at university level they tends to use "imaginary number to solve the problems" or phasers. So in more complicated scenarios, it might be easier. But as I said your way is the most understandable way for trade and EET students

nice explanation

Hello, Zack. Sorry to bother you again. Just to point out another subtle mistake in your video. It's a common mistake one can even find in some textbooks. The complex power consumed by a complex load is given by the phasor line voltage times the conjugate of the current through it. Thus for a lagging load, i.e. an inductive load, the complex power has a positive reactive component and hence a positive angle. This means that the power triangle must be drawn upright and not the way you have drawn it. And it's the other way round for a capacitive load.

Hi Zack, your explanation is so good. We are a startup looking forward to benefit students in India with your expertise. Can you share your email so I can send details. Thank you
