Kirchhoff's Current Law is a direct result of conservation of charge.
In the visualisation below, Kirchhoff's current law dictates that the current flowing into the node must be equal to the current flowing out of the node (represented by the black circle).
Edit the values of \(I_1, I_2, I_3, I_4\) and \(I_5\) and see how it affects the value of \(I_6\), which is given to two significant figures.
In addition, click any arrowhead to change the direction of the current through the relevant wire. Use this feature to explore the idea of negative current. For example, \(-8A\) flowing into a node is the same as \(+8A\) flowing out of a node. Note that the direction of \(I_6\) can also be reversed.
