Question

It is required to construct a 10 µF capacitor which can be connected across a 200 V battery. Capacitors of capacitance 10 µF are available but they can withstand only 50 V. Design a combination which can yield the desired result.

Answer 1

Answer: 4

Explanation:

Let there are ‘x’ no of capacitors in series

ie in a row So, x × 50 = 200 => x = 4 capacitors.

Effective capacitance in a row = 10/4

Now,

let there are ‘y’ such rows,

So, 10/4 × y = 10 => y = 4 capacitor.
