CBB film capacitor

Introduction to product description: Capacitors are components that store electricity and electrical energy (potential energy). A conductor is surrounded by another conductor, or the electric field lines emitted by one conductor all terminate in another conductor, which is called a capacitor. Product principle: In a DC circuit, a capacitor is equivalent to an open circuit. A capacitor is a component that can store electric charge, and it is also one of the most commonly used electronic components. This must start from the structure of the capacitor. The simplest capacitor consists of plates at both ends and an insulating medium (including air) in the middle.

product description:

Capacitors are components that store electrical energy and electrical energy (potential energy). A conductor is surrounded by another conductor, or the electric field lines emitted by one conductor are all terminated in the conductor system of another conductor, which is called a capacitor.

Product principle:

In a DC circuit, a capacitor is equivalent to an open circuit. A capacitor is a component that can store electric charge, and it is also one of the most commonly used electronic components. This must start from the structure of the capacitor. The simplest capacitor consists of plates at both ends and an insulating medium (including air) in the middle. After energizing, the electrode plates are charged to form a voltage (potential difference), but due to the insulating material in the middle, the entire capacitor does not conduct electricity. However, the premise of this case is that the critical voltage (breakdown voltage) of the capacitor is not exceeded. We know that any substance is relatively insulating. When the voltage across the material increases to a certain level, the material can conduct electricity. We call it breakdown voltage. Capacitors are no exception. When they are destroyed, they are not insulators. However, in the middle school stage, such a voltage is invisible in the circuit, so it works below the breakdown voltage and can be regarded as an insulator.
