Which of the following is a possible combination for resonance?
Correct answer: A. 4L, C/4
- A. 4L, C/4
- B. 2C, 2L
- C. 4L, 4C
- D. 2L, 4C
Explanation
Resonance depends on the product of L and C. In option A, the new product L'C' = (4L)(C/4) = LC. Since the product remains unchanged from an initial state (LC), it will have the same resonant frequency and is therefore a possible combination.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
