Resistance of Collector and Emitter (IGBT), also known as the on-state resistance (R<sub>on</sub>) , is the resistance that the IGBT presents to the flow of current. And is denoted by Rce(igbt). Resistance of Collector and Emitter (IGBT) is usually measured using the Kilohm for Electric Resistance. Note that the value of Resistance of Collector and Emitter (IGBT) is always positive.
