IB Physics: Circuits, component combinations and power

Here we use the law of conservation of energy to derive equations for combinations of resistors. Physical laws have far reaching consequences.This is quite a lot for one lesson, maybe being a bit optimistic here.Most students already know that R=R1 + R2 but very few can show how this is a consequence of the laws of physics. When deriving this we say that V=V1+V2, most students will say either that this is obvious or...
