    Electric elements are abstract representation of idealized electrical components. For example, resistors, capacitors, and inductors are used in the analysis of electrical networks. Any electrical network can be analyzed as multiple, interconnected electrical elements in a schematic diagram or circuit diagram, each of which affects the voltage in the network or current through the network.

    These ideal electrical elements represent real, physical electrical or electronic components but do not exist physically. They are assumed to have ideal properties according to a lumped element model, while components are objects with less than idea properties. A degree of uncertainty in the values and some degree of non-linearity will require a combination of multiple electrical elements in order to approximate its function.

    Circuit analysis using electrical elements is useful for understanding many practical electrical networks using components. But analysing the way the network is affected by its individual elements it is possible to estimate how a real network will behave.

    There are only nine types of elements, five passive and four active, which are required to model any electrical component or circuit. Each element is defined by a relation between the state variables of the network, current, voltage, charge and magnetic flux. There are only two sources, a current and a voltage source. The three passive elements are resistance, capacitance, and inductance. The active elements are, voltage-controlled voltage source, voltage-controlled current source, current-controlled voltage and current-controlled current source.
