High-Pass RC Filter Simulation | Understanding Frequency Response

In this video, we explore the working of a High-Pass RC (Resistor-Capacitor) Filter using a circuit simulation. A high-pass filter allows high-frequency signals to pass through while attenuating low-frequency signals.
We begin by constructing a simple RC series circuit using an AC voltage source, capacitor (C₁), and resistor (R₁). By varying the input frequency from 40 Hz to 3 kHz and changing the capacitance value, we clearly observe how the output voltage (measured across the resistor) changes.
This simulation helps you understand:
Frequency-dependent behavior of RC circuits
Cutoff frequency concept
Phase shift between input and output signals
This video is ideal for students, beginners, and electronics enthusiasts who want to understand filter circuits visually and intuitively.
