Question

Three identical capacitors are connected together differently. For the same voltage to every combination the one that stores maximum energy is

• A. the three in series
• B. the three in parallel
• C. two in series and the third in parallel with it
• D. two in parallel and the third in series with it

Answer 1

Answer: (B)

Energy stored in a capacitor $(U)=\frac{1}{2}C{V}^2$
$\therefore U\propto C$ Capacitance is maximum in parallel combination.
Therefore, maximum energy is stored in parallel combination.
