Wonderful video. Current is constant in a series circuit. Believe this was not
mentioned other than that Kirchhoff’s first law applies.

Learners would need to know this beforehand. Thank you.

In my head I said 2.2 amps for the whole circuit. This is before starting the video.


Got me, totally wrong on my part.

I have a question, 72V is gonna be the voltage from the battery or is gonna be the voltage remaining from the resistor of 40 ohms. I think is gonna be the voltage remaining from the resistor, is it right?
