resonant LC circuit

shaiqbashir

Consider a resonant LC circuit. It consists of a capacitor of capacitance 100pf and an inductance of 0.1mH. suppose that when the circuit oscillates the max. voltage on the capacitor is 1mV. Energy stored in the capacitor is given as 0.5CV^2.

a) Show that in this circuit one can obtain a quantity having the dimensions of action (same as Planck;s constant "h").

b) Obtain the value of this quantity and compare with "h".
the value you obtain must be larger than "h". Quantum Mechanics is applicable if the quantity is comparable to "h".
