Document Summary
Now let"s hook resistors up both in series and in parallel in the same circuit! So far we"ve just considered batteries and generators as contributing their emf to a circuit. In batteries it"s due to the chemicals, and in generators it"s due to wire resistance. So, if a battery is connected to a load resistor, r, then the internal ith th l d resistance, r, is in series with the load: i t i i i g. Thus, the voltage across the battery (known as the terminal voltage, vt) is less than the full voltage v, since some is lost across r. In many circuits, applying the series or parallel methods is not sufficient to analyze them. There are two other rules we can use called kirchhoff"s rules: 1 junction rule current into a junction has to equal current out: junction rule current into a junction has to equal current out.
