From Equation ref{8.4} it is obvious that the permittivity of the dielectric plays a major role in determining the volumetric efficiency of the capacitor, in other words, the amount of capacitance that can be packed into a given sized component. Unlike resistors, capacitors do not have maximum power dissipation ratings. Instead, they have
The capacitor gets charged through both resistors until 2/3 Vcc is reached (internal comparator level). This sets a flip-flop which activates the Discharge output (DIS). Through DIS and the potentiometer, the capacitor is discharged until the voltage on the Trigger input (TRI) is 1/3 Vcc, which resets the flip-flop and switches off DIS, so that
The role of a capacitor is to work as a frequency dependent impedance.For simplicity,not exactly correct, You can think of it as a frequency varying resistor. The impedance of the capacitor decreases as the frequency increases so at high frequency signals the capacitor has low impedance.
