Kirchhoff's Law KCL KVL

Gustave Kirchhoff  was an outstanding German Physicist  who contributed to Fundamental of electrical circuit, black body radiation by heated object and many more.

Kirchhoff's Laws  two in number. These laws are used for solving Electrical Networks which may not possible to solve by latter.

Kirchhoff's Current Law: KCL

It states that, in any electrical network, the algebraic sum of the currents meeting at a point is zero (0).

it simply means that the total current leaving a junction is equal to the total current entering the junction.

incoming current=outgoing current

Kirchhoff's Voltage Law or Mesh Law: KVL

it states that, The algebraic sum of the Products of the currents  and resistances in each of the conductors in any closed path or mash in a network plus the algebraic sum of e.m.f in that path is zero.

in other word, it states that, if we start from a particular junction and go around the mesh till we come back to the starting point, then we must be at the same potential with which we started.

∑IR+∑e.m.f = 0
