Alternating CurrentMedium
Question
In an ideal parallel LC circuit, the capacitor which is charge by connecting it to a D.C source which is then disconnected. The current in the circuit.
Options
A.becomes zero instantanously
B.grows monotonically
C.decays monotonically
D.oscillates instantanously
Solution
In an LC circuit current oscillates between maximum and minimum value. So, LCcircuit needs oscillations (electrical). It occurs due to discharging and charging of capacitor and magnetization and demagnetization of inductor.
