The frequency at resonance for the circuit is
Options
- A1 4 LC
- B1 2 LC
- C1 LC
- D2 LC
Correct answer
C. 1 LC
Step-by-step solution
For the resonant frequency of the LC circuit, the equivalent inductance for two parallel inductors each L is L eq = L 2 . The equivalent capacitance for two series capacitors each C is C eq = C 2 . At resonance, f = 1 2 L_ eq C_ eq = 1 2 L 2 C 2 = 1 2 LC 4 = 1 LC . Answer: C
