A capacitor of capacitance C, is being charged up by connecting it across a d.c. voltage source of voltage V. How do the conduction and displacement currents in this set up compare with each other (a) during the charging up process? (b) after the capacitor gets fully charged?

Explanation

From the property of continuty,
(a) Conduction current equals to displacement
currents. During charging up process, there is
a conduction current in connecting wires and
equivalent displacement current in the region
between the two plates of capacitor.
(b) After the capacitor gets fully charged., the
conduction current in the conneting wires
becomes zero. Now displacement current in a
region between the two plates is also zero due
to property of continuty.
