Elementary Row (Column) Transformations The following three operations applied on the rows (columns) of a matrix are called elementary row (column) transformations. (i) Interchange of any two rows (columns): If ith row (column) of a matrix is interchanged with the jth row (column), it will be denoted by Ri ↔ Rj (Ci ↔ Cj). For Example: , then by applying Read more about Elementary Row (Column) Transformations[…]
Solenoid and Toroid Solenoid: A solenoid is a coil of insulated or enamelled wire wound on a rod-shaped form made of solid iron, solid steel, or powdered iron. Devices of this kind can be used as electromagnets, as inductors in electronic circuits, and as miniature wireless receiving antennas. Let us consider a solenoid, such that its length is Read more about Solenoid and Toroid[…]

LC Oscillations The electric current and the charge on the capacitor in the circuit undergo electrical LC oscillations when a charged capacitor is connected to an inductor. The electrical energy stored in the capacitor is its initial charge which is named as qm. It is represented by The inductor contains zero energy. Charge varies sinusoidal with respect Read more about LC Oscillations[…]
Properties of Binomial coefficients Binomial Theorem: General form of a polynomial in x is an xⁿ + an₋₁xⁿ⁻¹ + … + a₁x + a₀, where an, an₋₁, …, a₁, a₀, are constants, an ≠ 0 and n is a whole number. A binomial is a polynomial which consists of two terms. Use Pascal’s triangle Properties of Binomial Coefficients (i) If ⁿCr = ⁿCs then either r Read more about Properties of Binomial coefficients[…]

Fundamental Rules for Differentiation Rule (I): Differentiation of a constant function is zero i.e., . Rule (II): Let f(x) be a differentiable function and let c be a constant. Then c.f(x) is also differentiable such that . This is the derivative of a constant times a function is the constant times the derivative of the Read more about Fundamental Rules for Differentiation[…]
Wheatstone bridge For measuring accurately any electrical resistance Wheatstone bridge is widely used. There are two known resistors, one variable resistor and one unknown resistor connected in bridge form as shown below. By adjusting the variable resistor the current through the Galvanometer is made zero. When the current through the galvanometer becomes zero, the ratio Read more about Wheatstone bridge[…]
