Question

42 A number of condensers, each of the capacitance lut
and each one of which gets punctured, if a potential
difference just exceeding 500 V is applied, are
provided. An arrangement suitable for giving
capacitance of 2uF across which 3000 V may be
applied requires at least.
(a) 6 component capacitors
(b) 12 component capacitors
(c) 72 component capacitors
(d) 2 component capacitors​

Answer 1
