    Kirchoff's first law_Junction rule or Current Law According to it the algebraic sum of currents meeting at a junction is zero. Convention:- #Incoming current are positive and outgoing current are negative. #Net incoming current =Net outgoing current i1+i2+(-i3)+(-i4)+(-i5)=0 (I1+i2)-(i3+i4+i5)=0 (i1+i2)=(i3+i4+i5) # K.J.L is based on conservation of charge. Kirchoff's second law_Loop law or Voltage law According to it "the algebraic sum of the changes in potential in complete traversal of a mesh(close loop) is zero".This law is based on that electrostatic force which is conservative in nature and the work done by it in any closed path is zero or we say that K.V.L or Loop law is based on conservation of energy.
