Why Do Capacitors Block Dc Current. capacitors are used in dc circuits for a variety of reasons. actually capacitor doesn’t block dc current, the capacitor makes potential difference high to very low (about 0) and stops the current. a simple way of thinking about it is that a series capacitor blocks dc, while a parallel capacitor helps maintain a steady voltage. when a capacitor gets charged fully and the voltage across it becomes equal and opposite to the dc input voltage, no more current can flow. 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. This means that at dc,. at the extremes we say that a capacitor acts like an open circuit at dc and a short circuit at high frequencies. In figure 2 below, capacitor c2 acts as a blocking capacitor in this voltage divider design with the output waveform around zero volts. a capacitor permits the passage of alternating current (ac) but blocks direct current (dc) because it stores energy in. Their ability to block dc while allowing ac to pass.
