BASIC DC CIRCUIT CALCULATIONSBasic DC TheoryExample: What value of resistance must be added, in parallel, with an 8W resistor to providea total resistance of 6W (Figure 28)?Figure 28 Example Parallel CircuitSolution:R_{X}RR_{T}RR_{T}(8)(6)8648224WVoltageDividerA voltage divider, or network, is used when it is necessary to obtain different values of voltagefrom a single energy source. A simple voltage divider is shown in Figure 29. In this circuit,24 volts is applied to three resistors in series. The total resistance limits the current through thecircuit to one ampere. Individual voltages are found as follows using equation (2-12).ES-02 Page 36 Rev. 0
