CBSE Class 12-science Answered
When an ideal capacitor is charged by dc battery, no current flows. However, when an ac source is used, the current flows continuosly. How does one explain this, based on the concept of displacement current?

Expert Answer
When connected to a dc battery, no current flows as capacitor offers infinite resistance to d.c .Whereas since a capacitor offers finite resistance to a.c, current flows through it when connected to an ac source.
On connecting the capacitor to an ac source , the electric field across its plates changes continuosly. The displacement current arises due to the change of electric field between the two plates of capacitor.
Displacement current,
