An AM radio tuning circuit has a coil with an inductance of 4.00 mH and a capacitor set at 7.50 *10^-⁶ $\mu$F. What frequency will it detect? A) 1520 kHz B) 919 kHz C) 550 kHz D) 750 kHz

Question

Quizplus · Accepted Answer

The resonant frequency of an LC circuit is given by the formula $ f = \frac{1}{2\pi\sqrt{LC}} $. Substituting L = 4.00 mH and C = 7.50 x 10^-6 F, the frequency is approximately 919 kHz.
