Webb2 dec. 2024 · V-I Characteristics of p-n Junction Diode. In forward bias condition p-type is connected to positive terminal of battery and the n-type to the negative terminal of the battery, there is a reduction in the potential barrier, in this condition. For germanium diodes, when the voltage is 0.3 V, and for silicone diodes, when the voltage is 0.7 V the ... WebbForward voltage for a diode varies only slightly for changes in forward current and temperature, and is fixed by the chemical composition of the P-N junction. Silicon diodes have a forward voltage of approximately 0.7 volts. Germanium diodes have a forward voltage of approximately 0.3 volts. The maximum reverse-bias voltage that a diode can …

Webb9 apr. 2024 · Application of PN Junction Diode. The junction which is the p-n junction diode can be used as a photodiode, the diode which is sensitive to the light when the configuration of the diode is reverse-biased. It can be used as a solar cell. When the diode is forward-biased, it can be used in LED lighting applications. WebbExplanation: When a P-N Junction diode is forward biased, the thickness of the depletion region becomes negligibly small. Thus, the resistance of the semiconductor decreases. 5. The current produced in reverse-bias is called as _____ a) Reverse Current b) Breakdown Current c) Negative Current rice literacy

WebbForward biasing of p-n junction diode offers low resistance. In the case of an ideal p-n junction, resistance is zero. So, the ohmmeter can measure zero resistance. 3. Find out the application of the diode. a) Oscillator b) Amplifier c) Rectifier d) Modulator View Answer. Answer: c Explanation: Diode is used as a rectifier. WebbWhen any type of P-N junction is in forward bias, a resistor R s must be connected in series with the diode. The function of the limiting resistance is to limit the forward … WebbForward bias occurs when a voltage is applied across the solar cell such that the electric field formed by the P-N junction is decreased. It eases carrier diffusion across the depletion region, and leads to increased diffusion current. In the presence of an external circuit that continually provides majority carriers, recombination increases ... red interlock
