The forward characteristic curve of a junction diode is shown in figure below:

Calculate the resistance of the diode at:
y= 0.5V

Text Solution

Verified by Experts

Whene V= 0.5 volt, then current (I) = 40 mA `=40 xx 10^(-3)A`
`therefore` Resistance of diode
`(R_(d))= (V)/(I) = (0.5)/(40 xx 10^(-3))`
`=12.5Omega`
