How to Solve a Kirchhoff's Rules Problem – Simple Example

We analyze a circuit using Kirchhoff’s Rules (a.k.a. Kirchhoff’s Laws). The Junction Rule: “The sum of the currents into a junction is equal to the sum of the currents out of that junction.” (Conservation of Charge) The Loop Rule: “The sum of the voltages around a closed loop is equal to zero.” (Conservation of Energy).
