Alternating Current Calculator

This is the series alternating current circuit worked out in full: a resistor, an inductor and a capacitor across one sinusoidal supply. Enter the supply voltage and frequency with R in ohms, L in millihenries and C in microfarads, and it returns the inductive and capacitive reactances, the impedance, the current, the phase angle, the power factor and the real, reactive and apparent power, along with the voltage sitting across each component. A second action takes only L, C and the series resistance and gives the resonant frequency, the quality factor, the bandwidth and the two half-power points. Everything assumes ideal parts at a single frequency, so a real coil's own winding resistance belongs in the R box.
