Which of the following is a resonant or tuned circuit?
Pick an answer to check it.
Answer: A. An inductor and a capacitor in series or parallel
A resonant or tuned circuit is made from an inductor and a capacitor, connected either in series or in parallel. It responds strongly at one frequency, called the resonant frequency. A voltage regulator or a resistor circuit is not tuned.
Tip: LC in series or parallel = tuned circuit.
