a) You are provided with three capacitors of values 4µF, 6µF, 30µF and 220V power supply. Connect the 4µF and 6µF in parallel; and then connect the combination to the 30µF in series. Connect the 220V power supply across this arrangement and find (i) the equivalent capacitance of the circuit formed, (ii) the voltage across 30µF, (iii) the charge on each capacitor.
