試題詳解

80. Capacitors store and release electric charge, and capacitors store energy in the electric field. Inductors also store energy (like capacitors). But inductors do it in a vary different way: by storing the energy in a magnetic field. Under an ideal circumstance, capacitor and inductor are used to work together most likely to
(A) serve as an oscillator
(B) stabilize a circuit’s performance
(C) reduce the loss of energy
(D) improve the quality of data transmission
