Question

A capacitor is connected across a battery, (i) Why does each plate receive a charge of exactly the same magnitude? (ii) Is this true even if the plates are of different sizes?​

Answer 1

a) The each plate of a capacitor receives charge of exactly the same magnitude

• The capacitor plates are generally connected in series.In series connection the charge would be same on every element in the circuit
• So the plates of a capacitor have equal charge

b) Yes the statement is true even in the case of different sizes of plates

• The capacitance of a capacitor depends on several factors such as area of the plates and also the separation between them
• The charge on the capacitor plates is independent on these factors and is sane on both the plates
