there are two kirchoffs laws 1)junction law ,2)voltage law

1)junction law :

in multi loop circute at the junction sum of all the currents go into the junction is equal to sum of all the currents come out to the junction.

2)voltage law:in aclosed loop the sum of all emfs and resistences across the loop or circuit is zero.

Dear Kalyan,

1.First law:The Vector sum of the all individual currents in junction is must be zero.It is also called junction law.

2.Second law:The vector sum of all potential differences in a closed loop is must be zero.It is also called voltage law.

dear kalyan..,

basically there are two laws of kirchoffs.

1)junction law :

in multi loop circute at the junction sum of all the currents go into the junction is equal to sum of all the currents come out to the junction.

2)voltage law:in aclosed loop the sum of all emfs and resistences across the loop or circuit is zero.

Image result for kirchhoff`s voltage law

Kirchhoff's voltage law (KVL) The sum of all the voltages around the loop is equal to zero. v₁ + v₂ + v₃ - v₄ = 0. This law is also called Kirchhoff's second law, Kirchhoff's loop (or mesh) rule, and Kirchhoff's second rule. The principle of conservation of energy implies that.sults

The principle of conservation of electric charge implies that: At any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node. or equivalently. The algebraic sum of currents in a network of condu
