Question

A battery of constant voltage is available. How to adjust a system of three identical capacitors to get high electrostatic energy with the given battery

• A. Two parallel and one in series
• B. Three in series
• C. Three in parallel
• D. Whatever may be combination, it will always have same electrostatic energy

Answer 1

Answer: (C)

Three in parallel

Answer 2

Electrostatic energy of the capacitor is given by $\frac{1}{2} C V^{2}$
Now, if three capacitors are in parallel combination, there equivalent capacitance will be maximum, So electrostatic energy of the capacitor will be maximum.
