Phasor

Okay kiddo, so you know how sometimes things move in waves? Like when you throw a rock into a pond and it makes ripples? Well, electricity can also move in waves, and we call these waves "signals."

Now, sometimes we want to study these signals to see what they're doing, but it's hard to look at them directly because they're moving so fast. So instead, we use something called a "phasor." A phasor is like a little arrow that shows us which way the signal is moving, and how strong it is.

Imagine you're playing a game of catch with a friend. When they throw the ball to you, it has a direction (which way it's going) and a speed (how fast it's going). A phasor is kind of like an arrow on the ball that shows you where it's going and how fast it's moving.

Phasors help us understand signals better because they let us see how different parts of the signal are moving relative to each other. It's kind of like if you were watching a dance performance and you wanted to understand how each dancer was moving to the music. By looking at a phasor, we can understand how the different "dancers" in the signal are moving together.

So that's what a phasor is, kiddo! It's like a little arrow that helps us understand how signals move.
