$$a)$$. The current at $$1$$ Volt is $$10$$ mA and at $$1.2$$ Volt is $$15$$ mA . The dynamic resistance in this region is    $$R=$$ΔVΔ$$i=(1.2-1)Volt(15-10)$$ $$mA=0.2Volt5$$ $$mA=40$$Ω$$b)$$. The current at $$2$$ Volt is $$400$$ mA and at $$2.1$$ Volt it is $$800$$ mA. The dynamic resistance is   $$R=$$ΔVΔ$$i=(2.1-2)Volt(800-400)$$ $$mA=0.1Volt400$$ $$mA=0.25$$Ω
