Seven capacitors each of capacitance 2 F are to be connected to obtain equivalent capacitance of ( 10 11 ) F . Which of the following combination is possible?

Options

  1. A3 in parallel and 4 in series
  2. B2 in parallel and 5 in series
  3. C5 in parallel and 2 in series
  4. D4 in parallel and 3 in series

Correct answer

C. 5 in parallel and 2 in series

Step-by-step solution

In SHM, V = A²-x² V = A ²- 4 ~A ² 9 = 5 ~A ² 9 3 ~V = A ^ 2 - 4 ~A ² 9 Dividing the above two equations give A^ = 7 ~A 3
