Detailed Solution
Download Solution PDFVI characteristics of a diode
The value resistance of a diode is equal to the slope of VI characteristics of the diode.
The slope of the diode is given by:
\(R_d={Δ V\over Δ I}\)
where, Rd = Diode Resistance
ΔV = V2 - V1 = Change in voltage
ΔI = I2 - I1 = Change in current
Calculation
Given, ΔV = 200 - 100 = 100 V
ΔI = 20 - 5 = 15 A
\(R_d={100\over 15}\)
Rd = 6.66 Ω
