In this example, we have four diagrams.
00:03
The first diagram is we have two batteries connected in series.
00:08
So we have positive, negative, positive, negative.
00:12
So the batteries are connected as this.
00:16
So let's just say this has some voltage.
00:18
We're not worried about the values of the voltage.
00:22
And then in diagram b, we have two batteries connected in parallel.
00:26
So that means we're going to have positive to positive and negative to negative.
00:34
So these are my two batteries in parallel, part of a little circuit here.
00:42
Our third diagram is going to be two resistors in series.
00:47
So we have r1 connected to r2, 1, r2.
00:54
So this will be battery 1, battery 2, battery 1, battery 2.
00:58
And then in our third diagram, we have two resistors connected in parallel.
01:04
So we have r1, r2.
01:08
Then we're given four different effects.
01:11
And we want to match each effect to each diagram.
01:14
So my first effect is this setup will increase current out of the cell or battery, but a power off does not affect others.
01:24
So i increases power off.
01:30
I guess i'll say is independent.
01:35
And this will be for the case of two resistors in parallel.
01:41
So for case d, when one of these resistors breaks, the current is still able to go through path 1.
01:48
Let's say resistor 2 fails...
