Two plates of area 377 104 m2 each are separated by a dista

Two plates of area 377 × 10^-4 m2 each are separated by a distance 42.1 × 10^-2 m. Calculate the capacitance of the capacitor.

_____ F

Solution

Capacitance for parallel plate capacitor is given as: C = KA₀/D

Here ₀ =8.854 x 10^-12 F/m

A = 377 x 10 ^ -4 m^2 and D =  42.1 × 10-2 m

Further k = 1 for air.

Substituting the values in the above relation, we obtain,

Capacitance = C = 377 x 8.854 x 10^-16 / 42.1 x 10^-2 = 79.29 x 10^-14 F
