Okay, in this problem we are trying to find the electric field at this location.
00:08
So we have these two plates, i guess they are probably.
00:12
Zero volts, and then we got 100 volts, 200 volts.
00:20
And the place we're trying to find the electric field is at that red dot there.
00:24
And these are one centimeter and one more centimeter apart.
00:32
Okay, so how are we going to go about this? well, let's think about an equation we could use.
00:41
We know that there's this equation that tells us the change in voltage is equal to the integral of e .d .l.
00:56
The negative integral, rather, without really getting into too much of the complexities here, if we assume the electric field is constant, then we get this equation...
