Uses of capacitors | Capacitance | RC circuit time constant and Coupling
Capacitor coupling (CR-coupling) In general large electronic circuits. It usually consists of many sections together. Each section is connected by the capacitor. Because the capacitor allows an AC signal (change) to pass. But blocks the DC signal (stable). This connection is called a coupling capacitor or CR-coupling.
