How is a potential barrier formed?
when a p-n junction is formed electrons from the neutral N type goes to neutral P type. In the junction there will not be any electron or hole. In the junction because of earning electrons, P side becomes negative(ion) , & N side becomes positive(ion). So there will be a potential deference . This is known as the BARRIER......
Do you need to use TC extension wire to connect a thermocouple or can you use shielded cable?
You must use thermocouple wire (of the same type as the thermocouple) to extend the circuit. If you switch to a different wire the point of connection between the two becomes a thermocouple junction itself, and the resulting voltage from that junction will skew your reading. You can use any wire to extend a thermocouple connection if you know the temperature of the junction where the thermocouple wire ends--this becomes the reference junction.
What is the medical definiton of McDonalds sign?
The uterus becomes flexible at the uterocervical junction at 7-8 weeks gestation.
A thermal electric cooler uses the?
Peltier effect to create a temperature difference by passing an electric current through a junction of two different materials. One side of the junction becomes cold while the other side becomes hot, allowing for heat transfer and cooling.
Why is that a space charge region in a pn junction at equilibrium is often made small?
The space charge region in a pn junction at equilibrium is often made small due to:to obtain a high junction capacitance;since the junction capacitance is inversely proportional to the width of the space charge region, the smaller the width, the larger the junction capacitance.to ensure easy diffusion of charge carriers;if the space charge region is made small, that is, the width is made small, the distance for diffusion also becomes short, then it becomes easy for the electrons to diffuse into the p-side and the holes into the n-side
What is principal of half wave rectifier?
Its working is based on the fact that the resistance of p-n junction becomes low when forward biased and becomes high when reverse biased. By: Prince rai

Is bhusawal junction larger junction than lucknow junction in India?
lucknow junction has more trains then bhusawal
What is junction temperature of the transistor?
The junction temperature is limited by the relationship between temperature and life, and the characteristics of the materials composing the transistor. Furthermore, transistors use minority carriers and thus are easily affected by temperature. In particular , if the temperature rises in a reverse-biased collector-base junction, carriers are generated without relation to the signal, the operating point shifts, and in the worst case thermal runaway occurs and the transistor becomes damaged. For this reason, the circuit must be designed so as to prevent the junction temperature from rising. Transistor deterioration occurs quickly when the junction temperature rises.
Which junction has least junction capacitance?
point contact has the least junction capacitance
