how does this power supply work?
Accepted answer

This is quite easy. Remember that BE voltage of a bjt is around 0.6V when active. The Zener has a 5.6V drop. So, the zener sets the base voltage of the transistor to be 5.6V, this makes the Emitter ...

All things are imperfect and an "ideal" is defined. e.g., an ideal resistor behaves as R = V/I. In the manufacturing process "quality control" is essentially figuring out how to get closer to the ...

In general, you can't because of the unknown function of the controller. In the case of a solar cell, there is little damage except back current, which, changes are, the controller deals with. ...
