RC Charging Circuit

RC Charging Circuit

This simulation demonstrates the transient behavior of an RC circuit — how a capacitor charges through a resistor when a switch is closed. Features an animated schematic with electron flow, real-time voltage and current graphs, and an SPDT switch to switch between charge and discharge modes.

Filter Frequency Response

Filter Frequency Response

Interactive Bode plot for RC low-pass and high-pass filters. Adjust R and C with sliders to see the magnitude response and cutoff frequency update in real time, with an animated frequency sweep cursor.
