The Total solution for NCERT class 6-12
In a parallel plate capacitor with airbetween the plates, each plate has an area of 6 × 10−3 m2 andthe distance between the plates is 3 mm. Calculate the capacitance of thecapacitor. If this capacitor is connected to a 100 V supply, what is the chargeon each plate of the capacitor?
Area of each plate of the parallel platecapacitor, A = 6 × 10−3 m2
Distance between the plates, d =3 mm = 3 × 10−3 m
Supply voltage, V = 100 V
Where,
= Permittivity of free space
= 8.854 × 10−12 N−1 m−2 C−2
Therefore, capacitance of the capacitor is17.71 pF and charge on each plate is 1.771 × 10−9 C.
