👉 Impedances are a fundamental concept in electrical engineering that refers to the resistance of an electric circuit. They are measured in ohms (Ω) and can be positive or negative. Impedance is used in various applications, such as signal processing, telecommunications, and control systems. In simple terms, impedances represent how much resistance there is in a circuit when current flows through it. The larger the impedance, the greater the resistance. This concept is crucial in designing circuits that can handle high levels
