If a current enters the negative terminal of a polarized capacitors, does the negative plate have to be fully charged before it passes through to the positive plate.
A polarized capacitor is a type of capacitor that is designed to operate with a specific polarity, meaning that the positive and negative terminals must be connected correctly in a circuit. They are typically used in DC circuits and are commonly found in electronic devices.
Current flows through a polarized capacitor in the same way it flows through a regular capacitor. When a voltage is applied to the capacitor, one plate becomes positively charged and the other becomes negatively charged. This creates an electric field between the plates, allowing current to flow through the capacitor.
If a polarized capacitor is connected with the wrong polarity, it can lead to the capacitor becoming damaged or even explode. This is because the electric field will be reversed, causing a buildup of charge and ultimately leading to a breakdown of the capacitor's dielectric material.
When a polarized capacitor is fully charged, the flow of current will stop. This is because the capacitor reaches its maximum capacity to store charge and the electric field between the plates can no longer be increased.
No, polarized capacitors should not be used in AC circuits as they are designed to work with a specific polarity. In AC circuits, the direction of the current changes constantly, so using a polarized capacitor could lead to damage or malfunction.
