What is the resonant frequency of an RLC circuit if R is 22 ohms, L is 50 microhenries, and C is 40 picofarads?
44.72 MHz
22.36 MHz
3.56 MHz✓Respuesta correcta
1.78 MHz
Explicación
Resonance occurs where the inductive and capacitive reactances are equal, which depends only on L and C; the 22 Ω resistance affects the Q and the bandwidth but not the resonant frequency. Substituting 50 µH and 40 pF gives about 3.56 MHz.
