Document Summary

If it"s a power question: using the passive sign convention, calculate power with. We can transform power circuits in a way. If we have a voltage source in series with a resistor, it can be represented by a current source in parallel with a resistor using ohm"s law. We can analyse circuits with more than one independent power source by splitting it into two identical circuits with only one of each power source. We would then add the results to find the superpositioned result. Thevenin deals with voltage sources, while norton deals with current sources. Any configuration of a voltage source and resistor in series can be equivalently transformed into a current source in parallel with a resistor. This is done by finding the nearest voltage and using a known resistance to calculate the current. (usually using node-voltage analysis again: combining these two numbers we have found, we can calculate the equivalent.
