Barrier potential in a P-N junction is caused by
(A) Thermally generated electrons and holes.
(B) Diffusion of majority carriers across the junction.
(C) Migration of minority carriers across the junction.
(D) Flow of drift current.
Ans:
Barrier potential in a P-N junction is caused through diffusion of majority carriers across the junction.
Illustrate the polarity of Barrier potential. The free electrons which cross over the junction recombine with the holes of p-type and uncover some of the negative ac
At what velocity a clock should move so that it seems slow by one minute in a day.
How to measure deflection in deflection magnetometer
1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. II. The relationship between an object''s mass m,
Describe Kirchoffs Current Law? Ans. It defines " the current flowing toward a point in a circuit have to be equal to the current flowing away from that point. I = I 1 + I
How is that circuit wont be broken even there is an air gap in between the parallel plates? Ans) In AC circuit capacitor offers resistance to current as aresistor would do in DC.
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
Consider a horizontal cylinder with diameter D and length L. The center of the cylinder is a distance a above the ground. A wall with length W and height H is located to the side o
Radio Waves: Radio waves are electromagnetic waves with large range of wavelength from a few millimetres to many meters.
When a plane is in flight, the entire weight of the aircraft is essentially supported by the wings. To help you with this problem, it will be best if you visualize holding a model
