Find the current I if both diodes are identical. Voltage V = 0.8V and let the reverse saturation current be 10-9A. Correct Answer 4.8mA

Since both diodes are identical VD = 0.8/2 = 0.4V Equation for diode current where I0 = reverse saturation current η = ideality factor VT = thermal voltage V = applied voltage Since in this question ideality factor is not mentioned it can be taken as one. Take VT as 0.026 which is the standard value. Hence current through one diode is 10-9x(e0.4/0.026) = 4.8mA.
