What is Kirchoff’s Current Law?

Kirchhoff’s Current Law (KCL) states that the total current entering any junction in an electrical circuit is equal to the total current leaving that junction. This fundamental principle implies that charge cannot accumulate at any node; whatever current goes into a node must also come out.

Kirchhoff’s Current Law (KCL) states that the algebraic sum of currents at any node or junction in an electrical circuit is equal to zero. This principle explains how KCL works in the context of the diagram below.

At Node I1+I6+I5=I2+I3+I4,

          I1+I6+I5-(I2+I3+I4)=0

Sum of Incoming Current=Sum of Outgoing Current.

Kirchhof’s Voltage Low:

Kirchhoff’s Voltage Law (KVL) states that the sum of voltages around every closed loop in an electrical circuit must be zero. KVL expresses the fact that electric fields are conservative, meaning that the total work performed in moving a test charge around a closed path in an electrical circuit is zero.

The KVL equation

V1+V2+V3=V             ( V1+V2+V3)-V=0
