The blocking property of the capacitor is inversely proportional to the frequency that means if supply frequency increases the capacitive reactance decreased so the capacitor will pass more current. Why does a capacitor block dc. Why Does A Capacitor Block Dc But Pass Ac Electrical Technology Can I Add A Dc Blocking Capacitor To The Baseband I Q Inputs Cb8g 1 0 01uf 30kv 50a Dry Type Compound Die Capacitor In this post we will discuss this kind of behavior of capacitorfirst we will consider dc supply connected to a parallel plate capacitor as shown in figure below. Why dc blocking capacitor . Why do capacitor block dc but allows ac. And similarly if there is a path taken from the ac source through the dc blocking cap and back to the ac source again then current will flow. A dc blocking capacitor just represents a short for ac only. Keep in min...
