Question

The plates of a parallel plate capacitor each have an area of0.40 m2 and are separated by a distance of 0.02 m. Theyare charged until the potential difference between the plates is3000 V. The charged capacitor is then isolated. Reference: Ref 19-8
Determine the value of the capacitance.

b. 9.0 ×10–11 F
c. 4.8 ×10–10 F
d. 1.8 ×10–10 F
e. 6.4 × 10–10 F The plates of a parallel plate capacitor each have an area of0.40 m2 and are separated by a distance of 0.02 m.

Explanation / Answer

C = A / d = (8.85e-12)(.40^2) / (.02) = 1.8e-10 Answer is D: 1.8e-10 F
