Course dashboard A diode has 3 mA at 0.6 V and 210 mA at 0.75 V. Find its reverse saturation current (Is) and 1 ideality factor (7). Assume V>Vị and take VT = 25 mV. Uyg Note that because of the approximations, your result might be slightly different than the correct answer. However, it should be very close to it; hence, in that case, simply go for the choice that is closest to your result. Lütfen birini seçin: O A. Is=1.04×10,77-1.99 O B. Is=1.208X10 -10, n=1.41 O C.
