SEMICONDUCTOR DIODE ESSAY: What are your observations on the given table. How forward bias condition and reverse bias condition affects voltage and current? This data is simulated using tinkercad. A series circuit with battery, 1 diode and 1 resistor (100ohms). You can notice in 2nd column the batteries used in every row. Tinkercad AA battery is equivalent to 1.50 volts. Note that they are only different with the number of batteries used but the resistor(100ohms) and diode remains one only.
