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. Energy is delivered from the source to the user on demand at the flick of a switch. Sometimes many circuit elements are connected to the same lead, which is the called a common lead for those elements.
7.3 Resistors in Series and in Parallel The two resistors R1 and R2 in Figure 7.3.1 are connected in series to a voltage source∆V. By current conservation, the same current I is flowing through each resistor. Figure 7.3.1 (a) Resistors in series. (b) Equivalent circuit.
