In this photo, several cords are plugged into a power strip. But what most people don’t know is that there is physics occurring. This power strip is a parallel circuit. That means if I were to unplug a cord, the other appliances would still work. But why is this? The reason is because, in a parallel circuit, every outlet is independent of the others.
Also, current, power, and voltage are occurring too. Current is flowing through the cords and power strip. Power is being used by the appliances that are plugged in. And voltage gives energy to charge power in the appliances.
Physics is all around us, even in the littlest things!
