    Series-parallel circuits

    The series-parallel circuit combines the two previously described types of circuits into one operating system with some distinct advantages. By introducing a load or resistor in series with a parallel circuit, the current flow through the circuit can be controlled (Figure 9).

      Using Ohm’s law you can calculate total current flow.

      I = E ÷ R

      I = 12 V ÷ 2.3 Ω

      I = 5.15 mA
