Hey guys, so to solve this problem, we're first going to draw a picture.
00:08
If that helps you, that helps me a lot because i'm very visual.
00:11
So i have drawn it out, but you can skip this part and just kind of write the information down if that works better for you.
00:18
So this problem mentions two different scenarios, i guess.
00:24
So we start with, i labeled it a, and that's just one capacitor.
00:31
By itself and then in b, which it moves to later on, you add a second capacitor in parallel with the first capacitor.
00:44
And from a to b, there's no change in the voltage or frequency of the generator, and the current decreases by a factor of three.
00:54
So that's how i just wrote out all the information.
00:57
You guys can do it however you want.
00:58
And then it asks us to find how the current would be delivered by the generator or how it would have increased once c2 is added in parallel.
01:17
So in that second scenario, basically how the current changes.
01:25
So to solve this problem, we're going to use this equation.
01:30
And then we can substitute x of c and end up with this equation and then simplify that into this final equation...
