In this method, Kirchhoff’s voltage law is applied to a network to write mesh equations in terms of mesh currents. The branch currents are then found by taking the algebraic sum of the mesh currents which are common to that branch.Kirchhoff’s Voltage LawThe Kirchhoff’s voltage law (KVL) states that, the ...
