Inverse matrix The transpose of the matrix obtained by replacing the element of the square matrix A by the corresponding cofactor is called adjoint of the matrix of A and it denote by adj(A) A square matrix A is said to be an invertible matrix if there exist a square matrix B such that AB Read more about Inverse matrix[…]
Transistor A transistor is a semiconductor device which is used to switch or amplify electronic signals and electric power. It consists of semiconductor material mostly with at least three terminals for connection to an external circuit. Transistor working principle: Transistors are made up of three parts namely a base, a collector and an emitter. The base serves Read more about Transistor[…]

Bandwidth of a Signal What is Bandwidth of a Signal? Bandwidth is a range of frequencies within a continuous set of frequencies. It is measured in Hertz. The purpose of a communication system is to transfer information from the transmitter which is located at one place to a receiver which is usually far away from Read more about Bandwidth of a Signal[…]
Total Internal Reflection Total Internal Reflection is a scenario where a travelling wave of light strikes a boundary of a medium but at an angle that is larger than critical angle. So, the concept behind is that if the refractive index on the other side of the boundary of the medium is lower, and the light wave Read more about Total Internal Reflection[…]

Resistors in Series and Parallel In an electric circuit, the different components can be connected either in series or in parallel to produce different resistive networks. Sometimes, in the same circuit, resistors can be connected in parallel and series, across different loops to produce a more complex resistive network. In the end, however, the total Read more about Resistors in Series and Parallel[…]
