Technician exam question T6D11
Subelement T6, ELECTRONIC AND ELECTRICAL COMPONENTS· Group T6D
Which of the following is a resonant or tuned circuit?
- A.An inductor and a capacitor in series or parallel (correct answer)
- B.A linear voltage regulator
- C.A resistor circuit used for reducing standing wave ratio
- D.A circuit designed to provide high-fidelity audio
WhyAn inductor and a capacitor in series or parallel form a resonant, or tuned, circuit. A resonant or tuned circuit is formed by an inductor and a capacitor connected in series or parallel, with energy exchanging between the two at the circuit's resonant frequency, answer A. A linear voltage regulator (B), a resistor circuit for reducing SWR (C), which isn't actually how SWR problems are solved, and a high-fidelity audio circuit (D) are all unrelated circuit types that don't describe an LC resonant combination.
