What is a unity power factor and what does it mean for the circuit?

Why is this guy better than a umich professor? Thanks!

[@gamelover2594]

another great explanation about electricity Mr. Zack :)

🎯 ty just what I needed

[@spelunkerd]

Why does power factor of a motor vary as the motor spools up? And how do you calculate the optimal capacitance values for parallel start and run caps? Is it just based on empirical power factor observations for a specific motor during startup?

[@ZackHartle]

I don't know for sure. I would assume it has to do with the counter EMF being different at different speeds

[@adamf1765]

i dont know what confuses me more, the way he write in the board or the power factor thingy. i thought the letters should be inverted if he is facing us.

Thanks 🙏🏼 for all

Why Q?

[@ZackHartle]

Stands for "Quadrature"

A low power factor means high costs to run your building or factory. $$$$. That’s why getting closer to unity is important.
