👉 Retardance is a property of electrical circuits that describes how much an electric field changes when it is applied to a conductor. It is measured in ohms (Ω) and relates to the resistance of the circuit to a change in voltage across it. In simple terms, if we apply a constant voltage across a circuit, the resistance R will increase because more charge must be moved through the material between the wires, which increases the current I through the circuit. When this current is changed by a small
