Common Emitter (CE) Configuration or Common Emitter Amplifier
WebHere for common emitter configuration output current is Ic and output voltage is Vcb. So, for common emitter connection, output resistance ( Ro) = change in Vce / change in Ic. Output Resistance = ΔVcb/ΔIc at constant base current ( Ib) As we see above in points of output characteristics, the output resistance of a circuit is high.
