For the reverse characteristics of the given p-n junction diode, a graph is plotted with reverse voltage along X axis and reverse current along Y axis. The principle behind the diode is similar to a valve or a gate, which lets electricity flow only in one direction (Simple English Wikipedia, Diode). /ColorSpace /DeviceRGB I-V characteristics I-V characteristics were introduced in the previous page when introducing Ohm’s law. stream This diode either made by silicon or germanium which has atomic number Z=14 or Z=32 respectively. Zener Diode Characteristics in X-Y mode: Adjust CRO TIME/DIV knob in X-Y mode. I t is noted that at a certain reverse voltage, the reverse current reaches its maximum level. I am aware that as a member of the academic community it is my responsibility to turn in all suspected violators of the honor code. %���� The symbol of a diode, shown in Figure A-1, looks like an arrow that points in the direction of current flow.

Full Wave Rectifier Name: Sanzhar Askaruly ID: 201100549 Date: 17/09/2014 Introduction Diode is an electronic device having conductor at their ends. Name Quantity Name Quantity 1 Diode (BY127, OA79) 1(One) No each DC Regulated Power supply (0 - 30 V variable) 1(One) No. 10M resistor (x 1) I. Diodes Overview Diodes are mostly used in practice for emitting light (as Light Emitting Diodes, LEDs) or controlling voltages in various circuits. However, unlike a resistor, a diode does not behave linearly with respect to the applied voltage as the diode has an exponential current-voltage ( I-V ) relationship and therefore we can not described its operation by simply using an equation such as … /Parent 17 0 R LIGHT EMITTING DIODE CHARACTERISTICS (SAMPLE LAB WRITEUP) John A.
