A parallel plate capacitor has a common plate area of 5 x 10\(^{-8}\)m2 and plate separation of 2 x 10\(^3\)m, Assuming free space,

What is the capacitance? [\(\varepsilon\)o = 9.0 X 10-\(^{-12}\)C2N-1m-2]

  • A. 2.25 x 10-17F
  • B. 4.50 x 10-17F
  • C. 2.25 x 10-16F
  • D. 4.50 x 10-16F

Correct Answer: A. 2.25 x 10-17F

Explanation

C = \(\frac{{\varepsilon}_oA}{d}\)

= \(\frac{5{\times} 10^{-8} {\times} 10^{-12}{\times} 9}{2 {\times}10^{-3}}\)

= 22.5 x 10-17F
