Kirchhoff’s law , Kirchhoff’s current law
Definitions
Node
A node or a junction in an Electrical circuit is a point where three or more connecting wires meet
Loop
A loop is any closed path in a circuit
Open circuit
Is an Electric circuit with one of the element is removed and the position remain open
Short circuit
Is an electric cicuit in which one of the element is by-pass with a wire. if R is by-passed with wire in the fig 1 above it is short-circuit.
Kirchhoff’s Current Law
Kirchhoff’s current law states that the resultant sum of the currents flowing into a node or junction is Zero. The total current flowing into a junction or node is equal to the total current flowing out of the same junction or node
See figure 2 above
Therefore
Mathematical ,
Kirchhoff’s current law states that
