What is an extrinsic semiconductor?
An extrinsic semiconductor is a material whose electrical conductivity is enhanced by doping it with impurities. These impurities introduce free electrons (n-type) or holes (p-type), significantly increasing charge carrier concentration compared to a pure, intrinsic semiconductor. For more visit herRead more

What happens to the width of depletion layer of a p – n junction when it is (i) forward biased, (ii) reverse biased?
(i) In forward bias, the depletion layer's width decreases as the applied voltage reduces the junction's potential barrier, allowing charge carriers to flow. (ii) In reverse bias, the depletion layer's width increases as the applied voltage strengthens the junction's potential barrier, preventing cuRead more
(i) In forward bias, the depletion layer’s width decreases as the applied voltage reduces the junction’s potential barrier, allowing charge carriers to flow.
(ii) In reverse bias, the depletion layer’s width increases as the applied voltage strengthens the junction’s potential barrier, preventing current flow.

Why is the conductivity of n-type semiconductor greater than that of the p-type semiconductor even when both of these have same level of doping?
The conductivity of an n-type semiconductor is greater than that of a p-type because electrons, the majority carriers in n-type, have higher mobility than holes, the majority carriers in p-type, even with the same doping level.

Why do liquids exert equal pressure in all directions?
According to Pascal’s law, the pressure exerted on a confined fluid is transmitted undiminished in all directions. This principle underlies hydraulic systems and other fluid applications. This question related to Chapter 9 physics Class 11th NCERT. From the Chapter 9. Mechanical Properties of FluidsRead more

Why does atmospheric pressure decrease with altitude?
As altitude increases, air density decreases due to reduced gravitational compression, leading to lower atmospheric pressure. This explains why breathing is harder at high altitudes. This question related to Chapter 9 physics Class 11th NCERT. From the Chapter 9. Mechanical Properties of Fluids. GivRead more
