A lamp is connected in series with a capacitor. What will happen if d.c.or a.c. is connected to current?

When an AC voltage of 220 V is applied to the capacitor C.

Three capacitors C_1,C_2 and C_3 are connected to a battery of 6 V as shown in the figure find the charge on three capacitor

A parallel plate capacitor is filled by a dielectric whose relative permittivity varies with the applied voltage (V) as epsilon = alpha V where alpha = 2V^-1 . A similar capacitor with no dielectric is charged to V_0 = 78 V . It is then concentrated to the uncharged capacitor with the dielectric. Find the final voltage on the capacitors.
