👉 A capacitor is a device used to store electrical charge. It has two plates, one at the negative end and one at the positive end. When an electric field is applied between the plates, it creates a voltage across the plates that can be used to store or release charges. Capacitors are often used in electronic devices such as mobile phones, computers, and other electronic appliances, where they store electrical energy for use later on. They also have applications in various fields like telecommunications, physics, and
