Solution

Input resistance may be defined as the ratio of small change in the base-emitter voltage (ΔVBE) to the resulting change in base current (IB) at constant collector-emitter voltage (VCE).

Input resistance`R_i=(DeltaV_(BE))/(DeltaI_B)`

To find the input resistance, mark a point P on the input characteristic. Now, draw a tangent at point P. The reciprocal of slope of AB will give the input resistance
