An introduction to Resistance.  We also define ohmic versus non-ohmic with graphs.  We define the slope of the graph as resistance.  There is also a discussion of a graph of Electric Potential Energy as a function of Position and we compare it to the Mechanical Energies in the Spacewarp.  Lastly, we derive the three equations for Electric Power.
