Question

07. in a parallel plate capacitor with air between the plates, each plate has an area of 6x16°
and the distance between the plates is 3 mm. Calculate the capacitance of the capacitor. If this
capacitor is connected to a 100 V supply, what is the charge on each plate of the capacitor?
​

Answer 1

Answer:

-3 2

Area of each plate A=6×10 m

Distance between the plates d=3mm=0.003m

Capacitance of capacitor C= C=

d

Aϵ

o

∴ C=

0.003

6×10

−3

×8.85×10

−12

=17.7pF

Voltage across the capacitor V=100 volts

Thus charge on each plate Q=CV

∴ Q=17.7×10

−12

×100

⟹ Q=1.77×10
