Q1: The current through a PN Junction diode with v volts applied to the P region to the N region, where (I0 is the reverse saturation current to the diode, m the ideality factor, k the Boltzmann constant, T the absolute temperature and q the magnitude of charge on an electron) is

A I0 (e-qv/mkT - 1)

B I0 e-qv/mkT

C I0 (1 - eqv/mkT)

D I0 (eqv/mkT - 1)

ANS:B - I0 e-qv/mkT

If given (diode voltage) Vd is positive, ans B. is correct, like wise Vd is negative then Id is -Io, if Vd is ZERO, then Id (diode current) =0.
