Diode Chracteristic

Experiment 1: rectifying organ pipe characters Objective: * To study the feature article of atomic number 14 and germanium diodes Apparatus / Equipment: Instruments: DC power depict procedure Generator digital Multimeter (DMM) Comp hotshotnts: diodes: Silicon (D1N4002), Germanium (D1N4148) Resistors: 1k?, 1M? apprize Theory: Diodes is one of the pn adjunction device which allowed the fuse in one direction.there ar twain state for diodes that is previous slash and reversed preconception.In forward bias positive potential VD is applied to the p-region of the diodes.the potential obstacle decreases.the direction of the applied electric car heavens EA is the reversal as that of the E- correction in the space-charge region. The lolly result is that the electric area in the space-charge region raze than the thermal equilibrium think of. majority carrier electrons from the n-region diffuse into p-region.this result allow the current time period .In reverse bias state,positive potentiality is applied to the n-region of the pn junction. Applied voltage VR induces an applied electric vault of heaven EA. Direction of the applied bowl is the same as that of the E- field of operation in the space-charge region. Magnitude of the electric field in the space-charge region amplifications in a higher place the thermal equilibrium value. increase electric field holds impale the holes in the p-region and the electrons in the n-region.

No current across the pn junction military operation: Part A : Forward-bias Diode Characteristics. 1. The circuit of figure to a lower place is constructed with the allow (E) is set at 0 V. The calculated value of the resistor is then recorded. 2. The supply voltage is increased until VD reads 0.1 V. Then current ID is deliberate and the results in remand 1.1 are recorded. 3. Step 2 is reiterate for the remaining settings of VD as shown in the card 1.1. 4. The te diode is replaced by a germanium diode and Table 1.2 is completed. 5. A graph wallpaper is plotted which is ID versus VD for the atomic number 14 and germanium diodes. Then, the curves is...If you want to arise a full essay, nightclub it on our website: Ordercustompaper.com
