Kirchhoff's loop law basically says that around any closed loop, potential difference of range in a certain way should be equal to zero.
00:17
The change of potential difference.
00:18
So i'll say that a different way to make it make more sense.
00:22
Let's say we had a regular circuit for things in series.
00:28
Here's our battery potential and let's say that this is r1, r2, and r3.
00:37
Okay, well, what kirchhoff's loop law says is that when you have something in series, especially like this, the potential of the battery minus the potential drop from every device in this circuit in series is going to be equal to zero.
01:07
In other words, the power that's applied by the battery can be distributed and will be distributed over all of the electrical devices in series.
01:19
So much so that by the time it goes through the last electrical device, it has no more potential energy.
01:28
Now, there is no difference between this point, call that point a for now, and this point.
01:37
There's no difference between these two points because the wire has zero resistance...
