Keep in mind that a capacitor act as a short circuit at initial stage and a fully charged capacitor behave as an open circuit. Capacitors resist a changes in voltage while inductors resist a change in current and acts as a short circuit in DC.
That can happen under DC but also under AC. A simple way of thinking about it is that a series capacitor blocks DC, while a parallel capacitor helps maintain a steady voltage. This is really two applications of the same behavior - a capacitor reacts to try to keep the voltage across itself constant.
Blocking an unwanted DC voltage occurs because the capacitor acts as an open to the DC voltage, not allowing it to pass through the dielectric. In Figure 2 below, capacitor C2 acts as a blocking capacitor in this voltage divider design with the output waveform around zero volts.
Coupling capacitors (or dc blocking capacitors) are use to decouple ac and dc signals so as not to disturb the quiescent point of the circuit when ac signals are injected at the input. Bypass capacitors are used to force signal currents around elements by providing a low impedance path at the frequency.
Electronic devices power our world and allow us to communicate. In all applications requiring signal integrity and accurate power amplification, blocking capacitors are used to provide clean waveforms and correctly amplified voltages. What Systems Rely on Stable Waveforms?
The maximum voltage is determined by the insulating barrier. Above a certain voltage it will breakdown and create a short circuit. That can happen under DC but also under AC. A simple way of thinking about it is that a series capacitor blocks DC, while a parallel capacitor helps maintain a steady voltage.
