In a parallel plate capacitor, if 10¹² electrons pass from one plate to another, a potential difference of 10 ~V is developed across the plates. The capacitance of the capacitor is

Options

  1. A0.16 10⁻⁸ ~F
  2. B1.6 10⁻⁸ ~F
  3. C16 10⁻⁸ ~F
  4. D0.8 10⁻⁸ ~F

Correct answer

B. 1.6 10⁻⁸ ~F

Step-by-step solution

Charge on each plate of capacitor has a magnitude, Q=N . e Here, N=10¹², e=1.6 10⁻¹⁹ Potential difference between plates, V=10 ~V Capacitance of capacitor, C= Q V C= N e V = 10¹² 1.6 10⁻¹⁹ 10 =1.6 10⁻⁸ ~F
