Find the applied voltage on a forward biased diode if the current is 1

1.	Find the applied voltage on a forward biased diode if the current is 1mA and reverse saturation current is 10^-10. Temperature is 25°C and takes ideality factor as 1.5.(a) 0.658V(b) 0.726V(c) 0.526V(d) 0.618VI got this question in an online quiz.The above asked question is from Characteristic Equation of Diode-1 topic in chapter Diode Circuit of Analog Circuits
Answer» RIGHT option is (d) 0.618V Easiest explanation: Equation for diode current I=I0×(e^(V/ηVT)-1)where I0 = REVERSE SATURATION current η = ideality factor VT = thermal voltage V = applied voltage VT at T = 25+273=298 is 298/11600 = 0.0256V, η = 1.5, I = 1MA, I0 = 10^-10A
