Explanation Given: The current changes from 0.1 mA to 10 mA . Concept used: The change in diode voltage if a change in current occurs is, V 2 − V 1 = V T ln I 2 I 1 ....... (1) Here, V 1 and V 2 are voltages, I 1 and I 2 are the currents and V T is the thermal voltage. Calculation: The value of thermal voltage V T at room temperature is approximately 26 mV . Substitute 10 for I 2 , 0.1 for I 1 and 26 for V T in equation (1) as, V 2 − V 1 = 26 ln 10 0

Analysis of Diode

It is a semiconductor device in electronics applications where only a one-way current is required. It is like a one-way switch that allows current to flow in one direction only. A diode has two terminals, a cathode, and an anode. The cathode is the negat…
