Kirchoffs law is used to determine the current of a complicated network and also to determine the voltage.
i. Kirchhoff's Point Law or Current Law (KCL)
It states that ''In any electrical network, the algebraic sum of the currents meeting at a point (or junction) is
zero.''
ii. Kirchhoff's Mesh Law or Voltage Law (KVL)
It states that ''the algebraic sum of the products of currents and resistances in each of the conductors in any
closed path (or mesh) in a network plus the algebraic sum of the e.m.f. in that path is zero.
