A parallel-plate capacitor has an area A = 2 × 10−4 m and a plate separation d = 1 mm
A parallel-plate capacitor has an area A = 2 × 10−4 m and a plate separation d = 1 mm. The permittivity of free space εo= 8.85 × 10−12 C2/Nm2. Its capacitance is
Right Answer is:
1.77 pF
SOLUTION
Given,
Area (A) = 2 × 10−4 m
Distance (d) = 1 mm = 10−3 m
C = εoA/d
The capacitance of a parallel plate capacitor is given by
C = (8.85 × 10−12 × 2 × 10−4)/10−3
C = 17.7 × 10−13
C = 1.77 pF
