What is the effect of increasing the inductance in an LC circuit on its resonant frequency?.
- A.The resonant frequency increases
- B.The resonant frequency decreases
- C.The resonant frequency remains the same
- D.The circuit becomes unstable
Model answer
What a good answer should say
- The resonant frequency decreases
Explanation
Why this works
Increasing inductance lowers the resonant frequency according to the formula f = 1/(2π√(LC)), where L is inductance and C is capacitance.
