This physics video tutorial provides a basic introduction into kirchoff's current law or junction rule. It explains how to calculate the missing current flowing into or out of a junction. A current flowing into the junction is given a positive sign and a current flowing out of a junction is given a negative sign. This video contains plenty of examples and practice problems on kirchoff's junction rule for KCl circuits.
