Question: In a damped oscillating circuit the energy is dissipated in the resistor. The _Q_ -factor is a measure of the persistence of the oscillator against the dissipative loss. (a) Prove that for a lightly damped circuit the energy, _U_ , in the circuit decreases according to the following equation. \frac{dU}{dt} = -2\beta U, where \beta = \frac{R}{2L}. (b) Using the definition of the _Q_ -factor as energy divided by the loss over the next cycle, prove that _Q_ -factor of a lightly damped oscillator as defined in this problem is  Q \equiv \frac{U_{\text{begin}}}{\text{Δ}U_{\text{one cycle}}} = \frac{1}{2\pi R}\sqrt{\frac{L}{C}}.
