Kirchhoff's rules have a wide range of applications, but they also have a number of drawbacks and restrictions. To begin with, many complex circuits necessitate extensive analysis. Kirchhoff's rules make it easier to simplify these circuits and determine unknown currents and voltages. These laws can be used for the practical analysis of any electrical circuit. But, like with anything, there are advantages and disadvantages. Kirchhoff’s law, however, has a number of drawbacks and limits. Kirchhoff’s law has a severe flaw in that it implies the closed-loop has no variable magnetic field. In the circuit, induction of emf or any electric fields is conceivable. The current and voltage rule will eventually fail as a result of this. KCL LAW has an impact on high-frequency circuits as well. Another problem is that KCL LAW is only valid and usable if the entire electric charge inside the circuit is constant.
