Now Playing: DC Circuit Analysis Voltage Divider
  • Description:  The sum of the voltages around a loop is zero. Need to label the polarities for each element. As you go around the loop, if you enter a + side then that would be a voltage drop from + to minus (algebraically that would be a positive value). If you enter with a -, that would be a voltage rise since youre going from - to + (algebraically that would be a -value). Adding up the voltage rise and drops will equal to zero. when going around the loop.
