For an R-L-C series circuit connected to an input signal of 4 Vp-p, 1 kHz periodic sinusoidal AC signal, the voltage drop across the resistor R measured with CRO displays a sine wave occupying 2 units total height with the volts/div knob at 1 V. What is the approximate RMS current for the circuit if R = 10 Ω?

The Q-Factor (Quality Factor) of a coil is a critical parameter in resonant circuits. How is it mathematically defined in terms of the coil's inductive reactance (XL) and its internal DC resistance (R)?
