Question

If the plates of a parallel plate capacitor are not equal in area, then quantity of charge

• A. on the plates will be same but nature of charge will differ
• B. on the plates as well as nature of charge will be different
• C. on the plates will be different but nature of charge will be same
• D. as well as nature of charge will be same

Answer 1

Answer: (A)

The charge stored on the capacitor depends on the potential difference between the plates
$Q \propto V$
Since the potential difference between the plates is same so the charges on both the plates are alike.
Due the difference in the area difference of the capacitor there will be fringing effect and the capacitance will vary not the charge.
$C =\frac{\varepsilon_{0} A }{ d }$
