Number counter Position Cut-off



In a DC circuit, the capacitor is equivalent to an open circuit. A capacitor is a component that can store charge and is one of the most commonly used electronic components.
This has to start with the structure of the capacitor. The simplest capacitor is made up of plates at both ends and an insulating dielectric (including air) in between. After energization, the plates are charged, forming a voltage (potential difference), but due to the intermediate insulating material, the entire capacitor is not electrically conductive. However, such a situation is under the premise that the threshold voltage (breakdown voltage) of the capacitor is not exceeded. We know that any substance is relatively insulated. When the voltage across the material increases to a certain extent, the substance can conduct electricity. We call this voltage the breakdown voltage. Capacitance is no exception. After the capacitor is broken down, it is not an insulator. However, in the middle school stage, such voltages are not seen in the circuit, so they all work below the breakdown voltage and can be viewed as an insulator.
However, in an AC circuit, the direction of the current changes as a function of time. The process of charging and discharging the capacitor is time-consuming. At this time, a varying electric field is formed between the plates, and this electric field is also a function of time. In fact, the current is passed between the capacitors in the form of an electric field.
