The charge on (4 F ) capacitor, in the given circuit is

Options

  1. A(24 C )
  2. B(100 C )
  3. C(2.4 C )
  4. D(30 C )

Correct answer

A. (24 C )

Step-by-step solution

The circuit can be redrawn as, (C_ cq = 4 6 4+6 =2.4 F ) As we know, potential drop across parallel branch (A B ) is (V_ A B =10 ~V ) So, charge (Q=C_ eq V=2.4 10 10⁻⁶ C ) (Q=24 C ) Since, in a series capacitor branch, there is equal storage of charge in each capacitor. So, (4 F ) capacitor store a charge of (24 C ). Hence, the correct option is (a).
