This physics video tutorial explains how to solve complex DC circuits using kirchoff's law. Kirchoff's current law or junction rule states that the total current entering a junction is equal to the total current leaving the junction. Kirchoff's voltage law or loop rule states that the sum of all the voltages around a loop must add to zero. You need to be able to distinguish a voltage drop from a voltage lift. In addition, you need to be familiar with ohm's law when dealing with loop rule using kirchoff's law. This video contains plenty of examples and practice problems on KCl & KVl circuit analysis.
