Answer to Question #341624 in Electric Circuits for raisen Vana

Question

A parallel-plate capacitor has an area of 100 mm² and the plates are separated by 100 μm . If the capacitor contains paper between the plates, what is its capacitance

Answer 1

$$C=\frac{\kappa\epsilon_0 A}{d}$$

$$C=\frac{3.7*8.85*10^{-12}*100*10^{-6}}{100*10^{-6}}=3.27*10^{-11}\rm F$$
