Question
A radio tuner has 400 ohms resistor, 0.50 mH inductor, and a capacitor with capacitance of 72 pF. All three elements are connected in series. A) find the resonance frequency for the circuit. B) find the reactance of the inductor and capacitor at resonant frequency. A radio tuner has 400 ohms resistor, 0.50 mH inductor, and a capacitor with capacitance of 72 pF. All three elements are connected in series. A) find the resonance frequency for the circuit. B) find the reactance of the inductor and capacitor at resonant frequency. A) find the resonance frequency for the circuit. B) find the reactance of the inductor and capacitor at resonant frequency.Explanation / Answer
AAt )resonance frequency wL=1/wC
w^2=1/LC=2.77*10^(10)
w=166666.667
frequency=w/2pi=26525.8 Hz
(B) at resonance
reactance of inductor =wL=83.33 ohm
of capacitor=1/wC=83.33 ohm
