A 7x10^-6F and 3x10^-6F capacitor are connected in series across a 24V battery? What voltage is required to charge a parallel combination of the two capacitors to the same total energy?
The voltage required is 11 V.
First calculate the total capacitance of each combination.
(Note that I did not convert the
Next calculate the energy stored in the series arrangement:
Now calculate the voltage that would give the parallel combination the same total energy stored (
