What happens if you connect the negative terminal to the P-type? In this video, we will explore what happens to a PN junction when it's P side is connected to negative terminal and N side to Positive terminal of a battery. This connection is called the reverse bias.

By convention, we define positive direction of current to be in the direction a positive charge would move. Electrons (with their negative charge) move in the opposite direction of the positive current arrow.

The way I've defined it so far, this will only work in right triangles. So if you're trying to find the trig functions of angles that aren't part of right triangles, we're going to see that we're going to have to construct right triangles, but let's just focus on the right triangles for now. So let's say that I have a triangle, where let's say ...
