When the forwward bias voltage of a diode is changed from `0.6` V to `0.7` V the current changes from 5 mA to 15 mA. Then its forward bias resistance is

If the forward bias voltage a p-n junction diode is changed form 0.7 V to 2.2 V, the forward current changes by 1.5 mA, the forward resistance of diode is

If the forward voltage in a semiconductor diode is changed from 0.5V to 0.7 V, then the forward current changes by 1.0 mA. The forward resistance of diode junction will be

If the forward bias voltage of a p-n junction diode is changed form 0.7 V to 2.2 V, the forward current changes by 1.5 mA , then the depletion layer is
