Multiple choice general knowledge

Which of the following describes one method of impedance matching between two AC circuits?

  1. Increase the power output of the first circuit

  2. Insert an LC network between the two circuits

  3. Reduce the power output of the first circuit

  4. Insert a circulator between the two circuits

B Correct answer
Explanation

LC networks (inductor-capacitor circuits) are commonly used to match impedances between AC circuits by providing reactive compensation. Circulators direct signals but don't match impedance, and changing power output doesn't address impedance mismatch.
