I know how to implement the method and so on, but i can't make any sense of it. The two ways we find out R(th) and V(th) seem to contradict each other. We find R(th) by looking at the whole resistance of the circuit from R(L) perspective, but the way we find V(th) sounds to me like finding the voltage of the LOOP in which R(L) is in, and not from R(L) perspective. I assumed that V(th) should be more like the voltage drop across the very R(L) resistor itself not the loop in which it is located. I spent much time trying to understand the logic behind the theorem but i need help. Appreciate your attention.
