In a multi-loop circuit, what principle does Kirchhoff's Current Law (KCL) describe?
In a circuit, a junction has three branches. Branch 1 has a current of 2 A flowing into the junction, and branch 2 has a current of 3 A flowing into the junction. What is the current in branch 3 if it is flowing out of the junction?
