Ncert Solutions Physics Class 12th

The concept of continuity is defined for a function  as a curve that is smooth and unbroken at every point in its domain. Mathematically, a function $f (x)$ is said to be continuous at a point $x = a$ if:

$\lim_ {x \to a} f (x) = f (a)$

What it means:

• The function is defined at $x = a$,

• The limit of the function exists as $x$ approaches $a$,

• And the limit is equal to the function's value at that point.

Students can check the NCERT Class 12 Maths Chapter 5 Continuity and Differentiability for better and deep understanding of the topic.

Students can use the Class 12 Electrochemistry notes to prepare for the exam and quick revision.

Students can download the Classification of metal conductors & semiconductor notes provided by the Shiksha experts through this article.

We can classify the metal, conductor, and semiconductor based on their ability of electrical conductivity. Metals are good conductors with a high electrical conductivity, while semiconductor lies between conductors and insulators. Moreover, insulators have low electrical conductivity

Semiconductor is a material that can act as a conductor or an insulator based on its properties. There are two types of semiconductors: Intrinsic and Extrinsic semiconductors.

In p-type doping a special atom is added called acceptors to a pure semiconductor, such as Silicon, to increase the number of holes where electrons are missing. For instance, each Silicon atom has 4 valence electrons to which you add a dopant that has 3 valence electrons, say Boron, which has 1 less electron than silicon. In this case, Boron will try to bond with 4 neighbouring atoms, but Boron has one less electron. This missing electron will be the hold. These holes can move when voltage is applied, and the semiconductor will conduct through holes instead of electrons.

Students can download the Class 12 Physics Chapter 13 Nuclei NCERT Solutions PDF from various online platforms or they can visit the Shiksha homepage.

These PDFs are useful for students who want to study anywhere even if there is no internet access, which makes it easier to practice important numerical problems related to decay laws, nuclear binding energy, and nuclear reactions.
