3.2. Physical and mathematical meanings of circuit elements

The circuit elements we shall use in forming a schematic diagram are those of electrical circuit theory. These elements and their mathematical meaning are tabulated in Table 3.1 and should be learned at this time. There are generators of two types. There are five types of circuit elements: resistance, capacitance, inductance, transformation, and gyration. There are three generic quantities: (1) the drop across the circuit element; (2) the flow through the circuit element; and (3) the magnitude of the circuit element [7].

Attention should be paid to the fact that the quantity a ˜ is neither restricted to voltage e ˜ nor b ˜ to electrical current
