Impedance is a measure of the opposition to the flow of an alternating current (AC) in an electrical circuit. It is a complex quantity that combines resistance, inductance, and capacitance. In simple terms, impedance is like a "brake" that slows down the flow of electrical energy. The more impedance in a circuit, the less energy is transmitted, and the greater the power loss. Impedance is measured in ohms (Ω) and is typically represented by the symbol Z.
