The Kirchhoff's circuit laws are what there are of better for compute the current and voltage in anywhere of a circuit? Or exist another theory more simple, more practice and more general?

Kirchhoff's circuit laws are fundamental principles in electrical circuit analysis that govern the behavior of currents and voltages in a closed circuit. They are named after German physicist Gustav Kirchhoff and are used to calculate and predict the values of currents and voltages in complex circuits.
Kirchhoff's first law, also known as the law of conservation of charge, states that the algebraic sum of currents entering and leaving a junction in a circuit must be equal to zero. This means that the total amount of charge entering a junction must be equal to the total amount of charge leaving the junction.
Kirchhoff's second law, also known as the voltage law, states that in a closed loop in a circuit, the sum of all voltage drops must be equal to the sum of all voltage rises. This law is based on the principle of conservation of energy and is used to calculate the voltage drops and rises in a circuit.
Kirchhoff's laws are applied in circuit analysis by using them to set up and solve a system of equations based on the circuit's topology. The equations are then solved using mathematical techniques such as substitution or matrix methods to determine the values of currents and voltages in the circuit.
Kirchhoff's circuit laws have a few limitations, such as assuming ideal circuit elements and not accounting for the effects of non-ideal components such as resistance, capacitance, and inductance. They also do not consider the effects of electromagnetic interference and cannot be applied to circuits with changing magnetic fields. Additionally, Kirchhoff's laws only apply to DC circuits and do not take into account the transient behavior of circuits.
