Hello students in the question we are given two capacitors we know in series equivalent capacitance it is given by formula 1 upon c equivalent it is equal to 1 upon c1 plus 1 upon c2 the c1 and c2 are two capacitances here we can write this is equal to 1 upon 2 .0 micro ferret plus 1 upon 4 .0 micro ferret.
00:37
We can write 1 upon c equivalent, it is equal to taking lcm 4 .0 micro ferret we would have in numerator 2 plus 1.
00:50
This comes out to be equal to 3 upon 4 .0 microferrette.
00:56
Or we have c equivalent, it is equal to 4 divided by 3 microferret.
01:02
So here we have in series same charge is present on the capacitors.
01:26
So here we have total potential difference it is equal to 8 volt.
01:34
So we can write total potential difference it is equal to potential difference across capacitor 1 v1 plus potential difference across capacitor 2 that is v2.
01:46
So substituting the values here we can write we know formula q it is equal to cv where q it is charged in capacitor c it is capacitance and v it is potential difference we can write v it is equal to q by c so we can substitute this value here we can write v it is equal to v1 that is u divided by c1 plus v2 that is 2 divided by c2.
02:19
Here q it is charge on the capacitors.
02:24
Here v it is equal to 8 volt...
