## Final Value Theorem and Its Application

Final Value Theorem is used for determining the final value of a Laplace domain function F(s). Though we can always transform a time domain function into Laplace domain to apply Final Value Theorem. According to Final Value Theorem, final value of a function i.e. value...

## Initial Value Theorem

Initial value Theorem is a very useful tool for transient analysis and calculating the initial value of a function f(t). This theorem is often abbreviated as IVT. The limiting value of a function in frequency domain when time tends to zero i.e. initial value can...

## 4 Most Asked Numerical Questions

In job interview often interviewer asks some numerical this is quit tricky and easy to answer without going into much calculation. In this post, I am going to discuss 3 most asked numerical questions in job interviews. These 3 questions are picked from my personal...

## Concept of Electricity – What is Current?

What is Current? Electric Current is defined as the rate of flow of net charge through the conductor with respect to time. The direction of current is conventionally is in the direction of flow of positive charge. It is the flow of charge per unit...

## What is Eddy Current? – Concept of Electromagnetic Damping

What is Eddy Current? The literal meaning of Eddy is a circular current. Thus the word itself means current having no definite circular loop. Eddy current is defined as the induced current on the surface of conductor in little loops or eddies due to changing...

## Concept of Self Inductance

Self Inductance or Inductance is defined as the property of a material due to which it opposes the flow of current through it. It is usually denoted by ‘L’ and its SI unit is Henry. How a material possess such property? To understand, let us...

## Equivalent Inductance of Parallel Connected Inductors

When the potential difference between the terminals of two or more inductors are same, it is said that they are connected in parallel. As potential difference or voltage across the terminals are same therefore current flowing through the inductors may or may not be same....

## Mutual Inductance – Perfect Coupling and Coupling Factor

Mutual Inductance Mutual inductance is defined as inductance of a circuit caused by mutual coupling with other circuit. Mutual coupling of two coils means that magnetic field produced by one coil is linking / crossing the other coil and vice versa. Mutual Inductance is generally...
