Limitations of Dimensional Analysis Dimensional Analysis can’t derive relation or formula if a physical quantity depends upon more than three factors having dimensions. It can’t derive a formula containing trigonometric function, exponential function, and logarithmic function and it can’t derive a relation having more than one part in an equation. Although dimensional analysis is very Read more about Limitations of Dimensional Analysis[…]
Applications of Dimensional Analysis Dimensional Analysis is also called Factor Label Method (or) Unit Factor Method as we use conversion factor in order to get same units. The basic concept of dimensions is that we can add or subtract only those quantities which have same dimensions. Also, two physical quantities are equal if they have same dimensions. 1) To find Read more about Applications of Dimensional Analysis[…]
Geometrical Applications of Differential Equation Geometrical Applications of Differential Equation: We also use differential equations for finding the family of curves for which some conditions involving the derivatives are given. For this we proceed in the following way Equation of the tangent at a point (x, y) to the curve y = f(x) is given Read more about Geometrical Applications of Differential Equation[…]

Parallelogram Law of Vector Addition If two vectors acting simultaneously at a point can be represented both in magnitude and direction by the adjacent sides of a parallelogram drawn from a point, then the resultant vector is represented both in magnitude and direction by the diagonal of the parallelogram passing through that point. If two Read more about Parallelogram Law of Vector Addition[…]
Differentiation of Determinants To differentiation a determinant, we differentiate one row (or column) at a time, keeping other unchanged. For example, if . Differentiation on both sides, . (or) , Similar results hold for the differentiation of determinants of higher order. Example: If , then prove that f’(x) = 3x² + 2x (a² + b² Read more about Differentiation of Determinants[…]

Conductivity of Semiconductor Semiconductors are the materials which have conductivity between conductors and non-conductors or insulators. In semiconductors, the conduction band electron and valence band hole participate in electrical conduction. Semiconductors can be compounds such as gallium arsenide or pure elements, such as germanium or silicon. 1) In intrinsic semiconductors ne = nh, both electron Read more about Conductivity of Semiconductor[…]
