48.What do we call the ratio of change in collector-emitter voltage to the resulting change in the collector current at constant base current, when the transistor is being used in Common Emitter configuration? [A] Input dynamic resistance [B] Output dynamic resistance [C] Output emitter Current [D] Input emitter Current Show Answer
EXPLANATION: From above it is clear that the output resistance(ro) is defined as the ratio of change in the collector-emitter voltage (ΔVCE) to the change in collector current (ΔIC) at a constant base current 'IB', it is given by.
