Two condensers, one of capacity C and other of capacity C / 2 are connected to a V -volt battery, as shown. The work done in charging fully both the condensers is

Options

  1. A1 4 C V^2
  2. B3 4 C V^2
  3. C1 2 C V^2
  4. D2 CV ^2

Correct answer

B. 3 4 C V^2

Step-by-step solution

Work done in charging fully both the condensers aligned & = 1 2 C V^2+ 1 2 ( C 2 ) V^2 & = 3 4 C V^2 aligned
