👉 The term "impetre" is a technical term in the field of electrical engineering, specifically related to circuit analysis and design. It refers to a particular type of transient current that occurs when a circuit undergoes a sudden voltage or current change. In electronics and circuits, an impetre can be defined as a surge or ripple that appears suddenly during a period of time between a steady state and the next voltage or current change in the circuit. This phenomenon is often referred to as a "rush-current"
