Question

An LC circuit is formed by connecting an inductor with inductance L to a capacitor with capacitance C. The potential difference across a capacitor is cap-C where Q is the charge stored in the capacitor. Similarly the potential difference across the inductor is Vind-L where I is the current through the inductor. This is shown in the figure with capacitance C g where Qis the char difference across theindtorisav, below. As illustrated, 1-2 Recall from Kirchoff's law that cap + V,nd = 0. If L-2.5 ×10-7Vs and C = 6.2 ×10-96 what is the natural frequency of oscillation of the charges? Answer in MegaHertz (powers of 10°Hz. This is the mechanism by which AM radios work. dt Answer: The correct answer is: 4.04

Explanation / Answer

From the relation for natural frequency of LC circuit,

natural frequency= 1 / (2*pi*((L*C)^1/2)) = 1 / (2*3.14*((2.5*10^-7*6.2*10^-9)^1/2)) = 4.04*10^6 Hz
