State Kirchoff Current law
Kirchhoff’s Current Law (KCL) states:
At any electrical junction (node), the algebraic sum of currents is zero.
In simple words ???? the total current entering a node is equal to the total current leaving the node.
Mathematical form
∑Ientering=∑Ileaving\sum I_{\text{entering}} = \sum I_{\text{leaving}}∑Ientering?=∑Ileaving?
or
∑I=0\sum I = 0∑I=0
Why this works
It’s based on the conservation of electric charge — charge can’t be created or destroyed at a node.
