When one applies the Kirchhoff loop rule, the algebraic sum of potential drops across the cells and resistors is zero. This is because of Law of conservation of mass and the law of conservation of energy.

Kirchoff's voltage law helps us to get current distribution in different parts of complex electrical circuits.

It also helps us to get effective resistance across voltage sources like batteries and thereby to determine

the net current drawn from voltage sources.

It would violate the law of conservation of energy if the algebraic sum of potential drops across the cells and resistors across a closed-loop was not zero

Application of Kirchhoff's law -

Kirchhoff loop law is used to find the value of current, potential difference, and internal resistance in the DC circuit.
Wheatstone bridge is the major application of Kirchhoff's law.
It is also used in mesh and node analysis.
