Okay, reducing the capacitance means that you are adding the capacitor in a series.
00:09
So when you want to add a capacitor in series to a circuit, you must break some connections to make space for the capacitor, new capacitor.
00:19
Now, when you add a capacitor in series, the net capacitance is given by 1 over c, which is c net.
00:30
I'll just say cn for net is equal to 1 over c1 plus 1 divided by c2 now we know the net capacitance is 1 ,600 and we know capacitance of one capacitor which is 2 900 now we need to find the value of c2 here now if you try to simplify this equation here you can see that c2 looks something like this.
01:17
That is 1600 times 2 ,900 divided by 2 ,900 minus 1600.
01:42
So if you carry this out, you can get the value 3 ,569...
