Question

explain kirchoffs law

Answer 1

Kirchoff's Current law or Kirchoff's First law states that the algebraic sum of the currents meeting at any junction in a circuit is zero. The convention is that the current flowing towards a junction is positive and the current flowing away from the junction is negative. Let 1,2,3,4 and 5 be conductors meeting at a junction O in an electrical circuit. 

Answer 2

Junction rule: at any junction the some of the current entering is equal to the sum of the current leaving.
There is no accumulation of charges at any junction.
The amount of current flowing in is equal to amount of current flowing out.
Loop rule: the sum of changes in potential around any closed loop involving resistors and cells in the loop is zero.
These are the two rules in Kirchoffs law
