plural of circuitoUn circuit is an electrical network ( interconnection of two or more components, such as resistors, inductors, capacitors, sources, switches and semiconductors ) containing at least one closed trajectory. Circuits containing only sources, linear components ( resistors, capacitors, inductors ) and distribution of nonlinear elements ( transmission lines or cables ) they may be tested by algebraic methods to determine their behaviour in direct current or alternating current. A circuit that has electronic components is called an electronic circuit. These networks are generally nonlinear and require designs and more complex analysis tools.
