Question:

A capacitor C 4.7×10-9 F is connected across a 2.7 mH inductor. What is the natural oscillation frequency of?

A capacitor C 4.7×10-9 F is connected across a 2.7 mH inductor. What is the natural oscillation frequency of?

Answer:

The natural frequency of oscillation (w) is the frequency at which the reactance of the cap equals that of the inductor: w*L 1/(w*C) w sqrt(1/L*C) f 1/{2*pi*sqrt(LC)} 44.68kHz
