A student constructs a circuit using three capacitors as shown in the given figure. What will be the effective capacitance between the terminals X and Y?

Options

  1. A1 F
  2. B4 F
  3. C9 F
  4. D11 F

Correct answer

B. 4 F

Step-by-step solution

In the given circuit, the 3 F and 6 F capacitors are connected in series. Their equivalent capacitance C_s is: C_s = 3 6 3 + 6 = 18 9 = 2 F This combination is connected in parallel with the 2 F capacitor. The effective capacitance C_ XY between terminals X and Y is: C_ XY = 2 F + C_s C_ XY = 2 F + 2 F = 4 F Answer: 4 F
