Question

A number of condensers each of the capacitance 1 micro farad and each of which gets punctured, if a potential difference just exceeding 500V is applied are provided.An arrangement suitable for giving a capacitance of 2 micro farad across which 3000V may be applied requires at least

Answer 1

Answer:

12

Explanation:

• Capacitors in parallel combination , Ceq=C1+C2    Thus TWO rows required.

• From Kirchoff's 2nd rule Max potential dropped by SIX condensers in series is  6*500 = 3000V

Condensers required=2*6=12 nos
