part2 :Reverse Bias
Procedure – Reverse Bias
1. Set up the circuit as above and set the voltage supply at 20 V.
circuit
2. The microammeter is used in this part of the experiment, as current values will be
very low when a diode is in reverse bias.
3. Adjust the potential divider to obtain different values for the voltage V and hence
for the current I.
4. Obtain at least six values for V (0-20 V) and for I using the voltmeter and the
microammeter. Higher voltage values are required for conduction in reverse bias.
5. Plot a graph of I against V and join the points in a smooth, continuous curve.
