Kirchoff’s voltage law

Kirchoff explained two basic laws for voltage and current (kcl kvl). It is known as kirchoff law. They are kirchoff’s current law and kirchoffs voltage law (kcl and kvl).

Short name of kirchoffs voltage law is KVL.

Kirchoff’s law (KVL) states that “Algebraic sum of all voltages for a close path is zero.”

Mathematically KVL is expressed that

Where M is the number of voltages in the loop.

Let, we start from voltage source V1 and consider from negative to positive is negative sign and positive to negative is positive sign.

Now applying KVL we get,

-V₁ + V₂ + V₃ + V₄ - V₅ + V₆ = 0

Or   V₂ + V₃ + V₄ + V₆ = V₁ + V₅

It means sum of voltage drops = sum of voltage rises.

This is an alternative equation of KVL law.
