Basic DC Theory BASIC DC CIRCUIT CALCULATIONSThe total resistance in a parallel circuit can also be found by using the equation (2-10).(2-10)1R_{T}1R_{1}1R_{2}1R_{3}....1R_{N}Example 1: Find the total resistance of a 4W, an 8W, and a 16W resistor in parallel (Figure 27).Figure 27 Total Resistance in a Parallel CircuitSolution:1R_{T}1R_{1}1R_{2}1R_{3}1R_{T}14181161R_{T}416216116716R_{T}1672.29WNote: Whenever resistors are in parallel, the total resistance is always smaller than any singlebranch.Rev. 0 Page 33 ES-02
