This simulation shows the current response of resistor (R), inductor (L), and capacitor (C) circuits when excited with the same sinusoidal voltage source at 1 kHz. The blue waveform represents the applied voltage, while the other curves represent the respective currents. In the resistor, the current (green) is in phase with the voltage, confirming Ohm’s law. For the capacitor, the current (orange) leads the voltage by 90°, indicating capacitive reactance. In contrast, the inductor’s current (red
