This simulation shows the behavior of a series RLC circuit excited by an AC source. The resistor (R), inductor (L), and capacitor (C) are connected in series, so the same current flows through all three components. The graph at the top represents the instantaneous voltages across R, L, and C as sinusoidal waveforms. The resistor voltage is in phase with the current, the inductor voltage leads the current by 90 degrees, and the capacitor voltage lags the current by 90 degrees. Because of these ph
