Alternating Current

Solution:

When a capacitor is connected to a voltage source in a $DC$ circuit, current will flow for the short time required to charge the capacitor.
As charge accumulates on the capacitor plates, the voltage across them increases, opposing the current. That is, a capacitor in a $DC$ circuit will limit or oppose the current as it charges.
When the capacitor is fully charged, the current in the circuit falls to zero.
