The unipolar capacitors can only be used in dc while bipolar can be used in dc and ac. The capacitor is properly sealed externally so that no ingress takes place. The body of each capacitor is marked for its capacity, voltage, and polarity. It is built to withstand mechanical shocks. The Basic Circuit of Capacitors
Basic properties of a capacitor (3): "the higher the frequency, or the higher the capacitance, the more easily current can pass" As we have seen, one of the basic properties of a capacitor is that it blocks DC and passes AC. However, the ability to pass current is not the same for every kind of current. It depends on the frequency of the ...
Capacitors – the word seems to suggest the idea of capacity, which according to the dictionary means ''the ability to hold something''.That is exactly what a capacitor does – it holds electric charge. But what makes it a common component in almost all electronic circuits? Let us break down the stuff behind capacitors to understand what it does and how one could …

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
How Does a Capacitor Work? For demonstration, let us consider the most basic structure of a capacitor – the parallel plate capacitor. It consists of two parallel plates separated by a dielectric.
