Understanding RC Circuits

What is an RC Circuit?

An RC circuit combines a resistor (R) and a capacitor (C) in series or parallel. These circuits are fundamental in electronics, used for filtering, timing, and coupling applications.

Key Characteristics

  • Time Constant (Ï„ = RC): Determines charging and discharging rates
  • Energy Storage: Capacitor stores electrical energy
  • Impedance: Complex resistance to AC current
  • Frequency Response: Filters different frequencies
