Question

Each plate of a parallel plate capacitor
has a charge q on it. The capacitor is now
connected to a battery. Pick out the
correct statement/statements:
(Score: 1)
i) The facing surface of the plates
have equal and opposite charges.
ii) The battery supplies equal and
opposite charges to the two plates.
iii) The two plates of the capacitor
have equal and opposite charges.

Answer 1

The potential difference across the capacitor will gradually become equal to that of the battery .The inner surfaces will have equal and opposite charges according to

Q=CV

Q=CV

where

V

V

is the potential difference across the battery.

But, what will be the charges on the outer surfaces of the two plates ?

I am not clear about the role of battery in affecting the charges on the surfaces of the plates.

Option a) Looks right - Not sure about the other options.
