1. Three capacitors 1 uF. 2 uF. and 3 uF are connected first in series. The same capacitors are
again connected in parallel. ) Compare their equivalent capacitance it) Which one gives larger
value of capacitance
2 A parallel plate air capacitor has a capacitance of 10 A 9F What potential difference is
required for a charge of 5 x 10-5C? What is the total energy stored in the capacitor?

So, the parallel equivalent is 7μF.
Thus, the ratio is
