Capacitor charging and discharging circuit

Taw =1000 * 10^-3 =1000/1000=1sec A capacitor stores electrical energy in an electrostatic field. A capacitor's ability to store energy is measured by its capacitance, C, which is measured in farads. Capacitors are widely used to filter or remove AC signals from a variety of circuits. Also, because capacitors take a predictable time to charge and discharge = 5 Taw , they can be used in a variety of time-delay circuits.
