If $$P-N$$ junction diode is connected in forward bias at $$1.5V$$ then $$40$$ mA and at $$2V$$ $$-60$$ mA of current are passing. If some $$P-$$ N junction diode is connected in reverse bias at $$2V$$ then $$0.0$$ μA and at $$4v$$ $$-$$ $$0.2$$ μA of current is passing then calculate resistance of diode in forward bias and reverse bias

Question

If  $$P-N$$ junction  diode is connected in forward bias at $$1.5V$$  then  $$40$$ mA  and  at $$2V$$ $$-60$$ mA   of current  are passing. If  some $$P-$$ N  junction diode is connected in reverse bias at  $$2V$$  then $$0.0$$ μA  and at $$4v$$ $$-$$ $$0.2$$ μA  of current  is passing then calculate  resistance of diode in  forward bias and reverse bias

Infinity Learn · Accepted Answer

Resistance of diode in forward bias  $$=$$ ΔVΔ$$I=2$$−$$1.5(60$$−$$40)$$×$$10$$−$$3=0.520$$×$$10$$−$$3=25$$Ω Resistance of diode in reverse bias  $$=$$  ΔVΔ$$I=4$$−$$22$$×$$10$$−$$7=22$$×$$10$$−$$7=107$$Ω

If P-N junction diode is connected in forward bias at 1.5V then 40 mA and at 2V -60 mA of current are passing. If some P- N junction diode is connected in reverse bias at 2V then 0.0 μA and at 4v - 0.2 μA of current is passing then calculate resistance of diode in forward bias and reverse bias
