Hello.
00:01
So to get the capacitance of the capacitor and c, which is the capacitance is going to be k, which is the dielectric constant, e, not epsilon, not the pentivity or free space, that's the area over d.
00:25
So here d is going to be the thickness.
00:30
So what we're basically doing here is just the substitutions.
00:35
We need to be very careful with the units.
00:41
We need to be working in mts.
00:45
Let's try that.
00:47
So the dielectric constant was given us 2 .1.
00:53
The relativity of free space is 8 .85 into the negative 12.
01:03
Now here is where the problem is.
01:06
So we're given here 3 .8 centimeters.
01:11
So we need to convert out of meters.
01:13
So we're going to multiply that by 10 to the negative 2.
01:19
That's a meters.
01:21
So that's just, you know, multiplying the size.
01:24
And then times breadth...
