Document Summary

Need to know how to do resistance reduction and kirchoff"s laws. First define nodes sections of wire that are separated by circuit components. Set 1 of the nodes (preferably bottom node) as the reference. Write current in vs current out equations for all nodes. Use ohm"s law to replace all currents and then solve. All voltages have to be referenced so if you go through n nodes then your voltage is (v1 - v2--vn) If current through node is unknown make a super node that consists of all unknown currents. Write a voltage drop vs rise equations for each loop. No two loops can share a current source define a super loop to go around the source and then define the current source as the sum of the 2 loops it is on. Superposition and linearity: circuits that have only linear elements are subject to superposition and can be looked at in multiple parts.
