Explain Static (DC) resistance and Dynamic (AC) resistance

For the forward biased diode characteristics shown in the figure, the dynamic resistance at I_(D)= 3 mA will be ………. Omega .

In a P-N junction , for a 0.2 V change in the forward bias voltage, the corresponding change in current is 20 mA. The dynamic resistance of the P-N junction is

In a P-N junction , for a 0.2 V change in the forward bias voltage, the corresponding change in current is 20 mA. The dynamic resistance of the P-N junction is

A transistor with alpha=0.98 is operated in common emitter circuit with a load resistance of 5" k"Omega . If the dynamic resistance of the emitter junction is 70Omega , the voltage gain and power gain will be
