RC Time Constants (Part 1) - Pulse Circuit Response - Inductors, Capacitors, Transformers Video Lecture

This simulation shows a classic RC circuit's response to a square wave input, highlighting how a resistor-capacitor network behaves under periodic switching. The input is a 1 Hz square wave, and the circuit consists of a 100 Ω resistor in series with a 1 mF capacitor. This forms a first-order RC low-pass filter with a time constant τ = R × C = 0.1 seconds. When the input signal suddenly jumps to a high level, the capacitor begins to charge through the resistor, causing the capacitor voltage to r
