Superposition theorem

Superposition theorem is a fancy way of saying that if we have a bunch of things going on at the same time, we can figure out what's happening to each thing on its own. Imagine you're playing with a bunch of toys – a ball, a car, and a doll.

If you roll the ball, the car might move a little bit too, because it's on the same surface. But if you only focus on the car, and forget about the ball and the doll, you can figure out exactly what will happen to the car as it moves along the surface.

This is kind of like what the superposition theorem does with electrical circuits. Just like toys can move and interact with each other, electrical current can flow and interact with different components in a circuit. But by breaking down the circuit into smaller parts and analyzing what's happening to each part separately, we can figure out what's happening to the entire circuit overall.

So, the idea of superposition is just to break down complex circuits into simpler parts, and then figure out what's happening to each individual part. Once we understand each part, we can combine it all back together to see what's happening to the entire circuit. Pretty neat, huh?!
