Question A-001-004-011

What is the value of inductance (L) in a parallel RLC circuit, if the resonant frequency is 14.25 MHz and C is 44 picofarads?

Correct Answer

2.8 microhenrys

Explanation

From fr = 1 / (2π√(LC)), L can be found by L = 1 / ((2πfr)^2 C). With fr=14.25MHz and C=44pF, L = 1 / ((2π × 14.25e6)^2 × 44e-12) ≈ 2.84e-6 H or 2.84 µH, approximately 2.8 µH.
