Circuits
An electrical circuit is type of electrical network that includes a closed loop providing a return path for the electrical current. There are various kinds of circuits such as resistive circuits, bridge circuits, digital circuits and integrated circuits to name a few. A circuit which is formed exclusively by resistors, ideal current and voltage sources is referred to as a resistive circuit. In such a scenario, there is a linear correspondence between current and voltage.
An electrical circuit comprising of resistors, voltage and current sources which are constant is known as a DC circuit. A circuit which diverges the current in the conductor into two parallel paths and then brings them together again into a single conductor causing the closure of the loop is referred to as a bridge circuit. Digital circuits are primarily used in digital devices and are the result of intricate Boolean functions based on logic.
Digital circuits have certain advantages such as allowing storage as well as retrieval of the information without the possibility of it being subject to degradation. An integrated circuit is a miniature form of electronic circuit comprising primarily of semiconductor devices and passive components.
