This law is also called Kirchhoff's first law, Kirchhoff's point rule, or Kirchhoff's junction rule (or nodal rule).
The principle of conservation of electric charge implies that:
flowing into that node is equal to the sum of currents flowing out of that node

or equivalently
{\displaystyle \sum _{k=1}^{n}V_{k}=0}
Similar to KCL, it can be stated as:
available in that loop.
emfThe algebraic sum of the products of the resistances of the conductors and the currents in them in a closed loop is equal to the total in any closed loop is equivalent to the sum of the potential drops in that loop, or:
emfsMore simply, the sum of the (voltage) around any closed network is zero, or:
potential differencesThe directed sum of the electrical
The principle of conservation of energy implies that
This law is also called Kirchhoff's second law, Kirchhoff's loop (or mesh) rule, and Kirchhoff's second rule.
The algebraic sum of currents in a network of conductors meeting at a point is zero.
