Kirchoff's current law

The total current entering a junction or a node is equal to the toal current  leaving the node .

In above figure some currents are entering junction-A and some currents are leaving junction-A.

Total current entering junction-A = I1 + I3 + I5

Total current leaving junction-A = I2 + I4

By Kirchoff's current rule ,   I1 + I3 + I= I2 + I4

Kirchoff's voltage law

The voltage around a loop equals the sum of every voltage drop in the same loop for any closed network and equals zero.

In the above closed loop circuit ABCD , let us find the sum of voltages by going through clockwise starting from A . We get

By Kirchoff's voltage law ,
