Electrical Engineering: Basic Concepts (6 of 7) Power in a Circuit

In this video I will explain the basic concepts of power in a circuit.

Next video in this series can be seen at:

Thank you for the videos. I'm hoping if I watch them enough times, the information will eventually stop going over my head 🤞

Hi Professor, thank you for your videos. They are very well done. In this one, however, there is a little flaw at 4:26m. You mention velocity in lue of voltage! Hope you dont mind me saying so!

Thank you very much Michel for your outstanding effort.

Current * Voltage not Current* velocity

Isn't 5A coming out of the plus the same thing as -5A going into the plus? I think you meant to distinguish that if 5A were being forced into the battery then it would be absorbing power?

Thanks sir you are wonderful my caie is tomorrow, fan from Pakistan

Very good video     Presentation is outstanding

Sir, battery produce power and sources/resistor/load consumes power then why we represent both in positive?
2:46 why we don't write Power consumed in negative? Like negative at 4:03(battery with opposite ends or current in different direction) Or this is just calculation and we are just considering magnitude here.

When you said there is negative power across the second battery; doesn't negative power always mean the device is consuming power? Cheers. My understanding is that a battery with negative power isn't actually supplying power to the circuit.

By (-20W) happened to go through the battery, does it recharge? hmmm

[fahamidaani]

sir can we use the same formula for battery and resistor
