Question

The forward characteristics curve of a junction diode is shown in Figure given below:

Calculate the resistance of the diode at:

(1) V=0.5 Volts

(2) I =60mA

Answer 1

(1) V = 0.5 volts

I corresponding to 0.5 volts is 40 mA.

(2) At I = 60 mA.

Voltage corresponding to I = 60 mA is 0.6 V.

= 0.01 x 103Ω

= 10Ω
