So what we're going to do is try to find the equivalent resistance of these three resistor values here on the left -hand side when they're put in series and when they're put in parallel to each other.
00:13
So what we have in this series circuit is we know that they're in series because there's an uninterrupted flow of current and i will just draw that path here.
00:25
So we know that since there's no breaking points or junctions, we know that they're in series.
00:31
And the equation for this is fairly straightforward, where all we have to do is actually sum them.
00:39
So i'll write the more general equation as a summation, and this is just simply saying that when you have resistors in series, you're going to basically just add them all up.
00:57
So we have here, when we use it for our case, we only have three.
01:01
So we're going to do r1 plus r2 plus r3, and that's going to give us 6 .6 kilooms.
01:20
So that would be the equivalent resistance of these three resistors in series.
01:27
And equivalent resistance, just to remind you, is if we were to sort of replace all of these resistors with just one resistor.
01:35
That would be the equivalent resistance...
