Alright, we need to do the equivalent resistance and figure out what the current is for that.
00:11
So we've got a resistor here at 186, there at 145, 150.
00:25
Always start from the back end and see about any current that either has to break or doesn't break at all.
00:37
So, highlighter, here we go.
00:39
So if we go to the back end, you've got some charges marching around, you've got some charges that are going to go through here.
00:45
They also have to go through here.
00:48
So those two are in series and you just add those resistances together to get the amount.
01:01
So 186 and 145 doesn't change.
01:05
And then you can put those two together to make 150.
01:13
Now if we look at the back two, you will see that a charge comes here and it has to split.
01:21
The charges have to split.
01:22
They have to decide if they're going to go this way or that way.
01:25
Are they going to go through this 145 or are they going to go through 150? you'll notice there's no other resistors there.
01:32
So when we're talking about parallel, you want to just have those two split, this one or that one.
01:36
Sometimes they do like three, but that's fine...
