This page contains a series of video tutorials about Kirchoff's rules for electrical electrical circuits. For this to make sense, you should have the basics skills listed below.

Necessary Background Skills
Video Camera Identify resistors in parallel or series (Actually this video discusses capacitors in series and parallel. But the rules are the same for identifying capacitors or resistors in parallel.)
Video Camera Reduce resistors in parallel to a single resistor
Video Camera Reduce resistors in series to a single resistor
Video Camera Identify what is the same for all resistors in series or parallel


Kirchoff's 1st Rule: the "Junction Rule"

Kirchoff's 2nd Rule: the "Loop Rule"


Video above is here:

Example 1 ...of the "Loop Rule"


Here is the video above:

Example 2 ...Using Both Rules

This example is shown in 3 videos. Below is part 1.

Using the TI-83 or TI-84

This video will show how to use your TI-83, TI-83+, TI-84, or TI-84+ calculator to solve for multiple unknowns with an equal number of equations. This uses "Reduced Row Echelon Form," "rref."

Thsi quiz assumes the defintion of a current as applied by physicists. Inother words energy always FLOWS from high potential energy to lower potential energy. This means that energy flows from the positive side of hte battery to the negative side. This is the same flow pattern that is described by the flow of positive charge.
