In the circuit shown, the inductor and capacitor are ideal and source has no internal resistance. The circuit is in resonance.
Options:(select one or more)
Answer:
A, C
Solution:
The circuit is initially in resonance, so .
A. Inserting a dielectric increases C, so decreases. Now , making the circuit inductive. Current lags voltage.
C. Inserting an iron rod increases L, so increases. Now , making the circuit inductive. Current lags voltage.
