### Output resistance of transistor when base current is constant Formula

resistance = -(Voltage across collector-emitter/Collector current)
R = -(VCE/Ic)

## Define the dynamic output resistance of a transistor amplifier in common - emitter configuration.

For a constant base current IB, the dynamic output resistance (r0 is defined as the ratio of the differential change in the collector-to-emitter voltage (ΔVCE) to the corresponding change in the collector current (ΔIc).
