Electric Fields: Crash Course Physics #26
As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating and a crucial part of physics.
==========
Last time, we talked about how charged particles exert electrostatic forces on one another. We calculated these forces using the charge of each particle: which can be either positive or negative, and the distance between them, and we did it with the help of Coulomb's Law: the equation that tells us the force generated by two charged particles on one another. But what if we want to talk about more that two charges, or if we're dealing with charged objects of various shapes and sizes? Coulomb's Law is great for finding the force between small objects, like particles but in physics, we deal with all sorts of shapes and sizes. Electric forces are used to bring power to your home, charge your computer, and light up the screen that you're using to watch this video. These everyd...
