What is capacitor? A capacitor is an electronic component that stores electrical energy. Think of it like a small rechargeable container for electricity. But it does NOT store electricity like a battery for long time. It stores energy for a very short time and releases it quickly. A capacitor has two metal plates with a small space between them. When electricity is applied: One plate becomes positive The other becomes negative Energy is stored between them
