Resonance frequency is possible at how many combination of inductor & capacitor.
Correct answer: D. Infinite
- A. Two
- B. Three
- C. Four
- D. Infinite
Explanation
The resonance frequency of an LC circuit is determined by the formula f = 1 / (2π√(LC)), where 'L' is the inductance and 'C' is the capacitance. This means that for any given resonance frequency, there are infinite combinations of inductance and capacitance values that can satisfy this equation, as long as their product remains constant. Therefore, the correct answer is that there are infinite combinations. The other options are incorrect because they suggest a limited number of combinations, which is not the case.

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.
