THEORY: The positive supply is connected to the anode and a negative supply to the cathode of the PN Semiconductor diode is called Forward Bias. Increase the +ve supply to anode, the depletion region width decrease and conduction of electron increase. The VI characteristics may be obtained by performed DC sweep analysis. The applied voltage is vary from an initial value of 0 to stop vale of 1 V in the step of increment 0.1v. To get VI characteristics, the currents corresponding to varying input voltages are noted and VI graph is observed in the output graph.

PROCEDURE: Double click the multisim icon. Select virtual components. Click power source icon and select DC power supply. Click diode family icon and select virtual diode.
