To calculate the maximum source circuit current, Code requires you to multiply the rated Isc value by 125%. This multiplier takes into account increased irradiance values and the ability of the module ...

This circuit contains a 5 Ω resistor in series with two resistors, 6 Ω and 4 Ω, which are in parallel. Start by calculating the combined resistance of the two parallel resistors.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
