Do you expect a kid to understand thevenin's theorem and Kirchoff's law ???
Kirchoff's Law, certainly.
If he can't, we might as well quit commenting on this thread because that is exactly what we are trying to explain. What we call it is irrelevant. It might as well be called Bugs Bunny's Law.
And I would certainly expect him to understand Kirchoff's Law and how it applies to a very simple, two or three resistor series circuit before I would a circuit combining components that behave in mathematically different ways.
So my question to you is, do you really expect a child to understand the behavior of PN a junction in a light emitting diode and how it behaves in a series circuit BEFORE he understands how two resistors behave in a series circuit?
