When selecting capacitors for a voltage divider, ensure that they have an adequate voltage rating to handle the expected input voltage. Power Dissipation: Capacitive voltage dividers are not suitable for high-power applications as capacitors have limited power handling capability. For high-power applications, resistive voltage dividers …
Operation of common emitter amplier. The common emitter amplifier circuit comprises of a voltage divider bias and coupling capacitor C B and C C at the input and output and a bypass capacitor C E which is connected from the emitter to the ground. The capacitor C B couples the input signal to the input port of the amplifier. It also separates the AC signals …

voltage, to be reduced by the divider. The interesting fact from Equation (1) is that even if the capacitor is a frequency dependent component the frequency does not appear. This is due to the fact that the capacitive divider components are all equally affected by frequency, hence, the frequency dependence of the output voltage disappears.
