Schematic 6: Series-Parallel Wiring As we can see in the diagram above, Zspk2 and Zspk3 are in series (2). Thus we can add them and replace them with a new impedance which we can refer to as Zspk2'.

Because, unlike a simple string of lights in a series circuit ... This circuit and circuit diagram contain a cell and two lamps connected in parallel In a parallel circuit, if a lamp breaks ...
