The connection between the supply and the load is made by soldering with wires that are often called leads, or with many kinds of connectors and terminals.
those elements. Various parts of the circuits are called circuit elements, which can be in series or in parallel, as we have already seen in the case of capacitors. Elements are said to be in parallel when they are connected across the same potential difference (see Figure 7.1.1a). Figure 7.1.1 Elements connected (a) in parallel, and (b) in series.
