Vc is usually used to refer to the voltage at the Collector with respect to "ground"; while Vce is usually used to refer to the voltage difference between the Collector and the Emitter.I don't understand what you're explaining MikeMi. Where is Vc?
There where is Vcc?Vc is usually used to refer to the voltage at the Collector with respect to "ground"; while Vce is usually used to refer to the voltage difference between the Collector and the Emitter.
Ok, that's what I thought and what the OPs original question was I think. He was wondering why it's called Vcc and not just Vc. As in why two c's?Vcc is just another name for Vc.
No, Vcc is the supply name, and Vc is the Collector voltage. There is usually a resistor between these nodes in most CE transistor circuits, so they are not the same node or the same voltage.Vcc is just another name for Vc.
