A parallel plate capacitor has a common plate area of 5 x 10-8m2 and plate separation of 2 x 103m, Assuming free space, What is the capacitance? [\(\varepsilon\)o = 9.0 X 10-12C2N-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 option: c
C = \(\frac{{\varepsilon}_oA}{d}\)
= \(\frac{5{\times} 10^{-8} {\times} 10^{-12}{\times} 9}{2 {\times}10^{-3}}\)
= 22.5 x 10-17F
= \(\frac{5{\times} 10^{-8} {\times} 10^{-12}{\times} 9}{2 {\times}10^{-3}}\)
= 22.5 x 10-17F
