(a)[3]
Explain the meaning of the capacitance of a parallel plate capacitor.
(b(i))[1]
A parallel plate capacitor $C$ is connected in the circuit shown. The ammeter reads $4.5\,\mu\text{A}$. Find the charge, in coulomb, that passes through the ammeter in $1.0\,\text{s}$.
(b(ii))[1]
Find the charge on one plate of the capacitor each time it is charged.
(b(iii))[2]
Find the capacitance of capacitor $C$.
(c)[2]
A second capacitor with capacitance equal to capacitor $C$ is now connected in series with $C$. Suggest and explain the effect on the current shown by the ammeter.
