The resistor-capacitor (RC) Circuit

An RC circuit is an electronic setup with a resistor and a capacitor connected together, controlling how electrical energy flows. The resistor limits current flow, while the capacitor stores energy in an electric field. When power is applied, the capacitor gradually charges through the resistor, and when power is removed, the stored energy is released. This process creates a delay or gradual change in voltage, useful for timing and filtering signals. RC circuits are fundamental in electronics for managing how signals develop or fade over time, serving as basic building blocks in many electronic devices.
