10.4: Kirchhoff's Rules - Physics LibreTexts
Kirchhoff’s first rule—the junction rule. The sum of all currents entering a junction must equal the sum of all currents leaving the junction: \[\sum I_{in} = \sum I_{out}.\] Kirchhoff’s second rule—the loop rule.
Kirchhoff's circuit laws - Wikipedia
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 equivalently:
Kirchhoff’s First Law - Junction Rule, Current Law, Nodal Rule
Kirchhoff’s first law goes by several names as Kirchhoff’s Current Law (KCL), Kirchhoff’s Junction Rule, Kirchhoff’s point rule, Kirchhoff’s nodal rule. It is an application of the principle of conservation of electric charge. The law states that at any circuit junction, the sum of the currents flowing into and out of that junction are equal.
Kirchhoff's Current Law, (KCL) and Junction Rule
Junction one occurs at node B, and junction two occurs at node E. Thus we can use Kirchhoff’s Junction Rule for the electrical currents at both of these two distinct junctions, for those currents entering the junction and for those currents flowing leaving the junction.
20.3: Kirchhoff’s Rules - Physics LibreTexts
Kirchhoff’s junction rule, also known as Kirchhoff’s current law (KCL), Kirchoff’s first law, Kirchhoff’s point rule, and Kirchhoff’s nodal rule, is an application of the principle of conservation of electric charge.
10.3 Kirchhoff’s Rules – University Physics Volume 2
Kirchhoff’s first rule, also known as the junction rule, applies to the charge to a junction. Current is the flow of charge; thus, whatever charge flows into the junction must flow out. Kirchhoff’s second rule, also known as the loop rule, states that the voltage drop around a loop is zero.
21.3 Kirchhoff’s Rules – College Physics chapters 1-17
Kirchhoff’s first rule—the junction rule: The sum of all currents entering a junction must equal the sum of all currents leaving the junction. Kirchhoff’s second rule—the loop rule: The algebraic sum of changes in potential around any closed circuit path (loop) must be zero.
