To determine total resistance in a series-parallel circuit, identify the series and parallel relationships, and then apply the formulas for series resistance and parallel resistance. To find the total current, apply Ohm's law and divide the total voltage by the total resistance. To determine branch currents, apply the current-divider formula, Kirchhoff's current law, or Ohm's law. Consider each circuit problem individually to determine the most appropriate method. Summary To determine voltage drops across any portion of a series-parallel circuit, use the voltage-divider formula, Kirchhoff's voltage law, or Ohm's law. Consider each circuit problem individually to determine the most appropriate method. When a load resistor is connected across a voltage-divider output, the output voltage decreases. The load resistor should be large compared to the resistance across which it is connected, in order that the loading effect may be minimized. To find total resistance of a ladder network, start at the point farthest from the source and reduce the resistance in steps. Summary Opens and shorts are typical circuit faults. Resistors normally open when they burn out. Bleeder current: The current left after the total .
