This physics video tutorial provides a basic introduction into kirchoff's voltage law which states that the sum of all the voltages in a loop must add to zero. This video explains how to solve kcl circuits by using kirchoff's loop rule to calculate the current flowing in a series circuit with multiple batteries / voltage sources. This video also explains how to calculate the electric potential at every point using ohm's law. This video contains plenty of examples and practice problems.
