How to Differentiate Between PNP & NPN Transistors [With Video]

It’s often Electronics and Communication engineering student get’s confused with the PNP and NPN transistors. Both of them are bipolar junction transistors. Also known as BJT transistor in short.  PNP and NPN transistors are...

Circuit Theory : Superposition Theorem

In this blog we are going to describe the Superposition theorem. The superpostion theorem is one of the fundamental theorems in circuit analysis. Superposition theorem is one of those strokes of genius that takes...

Introduction and Explanation of Reciprocity Theorem

Reciprocity Theorem states that – In any branch of a network or circuit, the current due to a single source of voltage (V) in the network is equal to the current through that branch...

Introduction and Explanation to Kirchhoff’s Current Law (KCL)

Kirchhoff’s Current Law also known as KCL is the Kirchhoff’s first law, it is sometimes also known as Kirchhoff’s point rule or junction rule. It is a fundamental law of electrical and electronics engineering.  Anyone...
