Kirchhoff's circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work … Meer weergeven This law, also called Kirchhoff's first law, or Kirchhoff's junction rule, states that, for any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node; or … Meer weergeven • Electronics portal • Duality (electrical circuits) • Faraday's law of induction Meer weergeven Kirchhoff's circuit laws are the result of the lumped-element model and both depend on the model being applicable to the circuit in question.
