In the image above, the arrow indicates the direction of current when the diode is under forward bias. Apparatus:-Experimental kit and patch cords. Materials Required. A PN junction is said to be forward-biased when the p-type region of a junction is connected to the positive terminal of a voltage source and the n-type region is connected to the voltage source’s negative terminal.. Forward Biased PN Junction Diode. The potential barrier of this p-n junction is reduced when a forward-bias voltage is applied to it. Forward and reverse characteristics at room temperature: Turn on the temperature control unit and set the temperature switch to \(25^oC\).The power supply for the p-n junction has two independent outputs and two independent voltage control knobs for forward and reverse operation respectively. When a diode is connected in a Forward Bias condition, a negative voltage is applied to the N-type material and a positive voltage is applied to the P-type material. Result: Volt-Ampere Characteristics of P-N Diode are studied. Select the diode … If this external voltage becomes greater than the value of the potential barrier, approx.
