WebbThe diode current in a p-n junction is modeled exponentially (given below.) When the p-n junction is polarized with 0.7V and 0.75V, the currents flowing through the diode are again measured on the basis of 1.36 mA and 7.20 mA. Accordingly, what is the ideality factor? (Note: Take the thermal voltage as mV)
