Re active energy and harmonics explain with a car

Re active energy and explained with a car

How to understand & re active energy

Are you a driver? I am sure yes, therefore you will understand power harmonics right away

Imagine a straight road, flat, a perfectly smooth surface, a constant speed. Your car works well, consumes as little as possible, and can run indefinitely.
It’s like an electrical grid with a constant power without harmonics.
