Electrical Circuits

It is a complex conductor between positive and negative terminals; It is said that current flows from positive to negative, although in fact the flow of electrons goes from negative to positive. If bind electrics, such as light bulbs and switches and connect the ends (positive to negative) poles we have a connection in series. Connecting the Poles (negative to positive and negative to positive) is a parallel connection.

Gustav Robert Kirchhoff

(March 12, 1824 – October 17, 1887) this German physicist has made massive contributions to the fundamental understanding of black-body radiation emitted by heated objects, spectroscopy, and electrical circuits. He also worked with other famous names in science and came up with other profound breakthroughs and theories. Indeed, he is a man who made great leaps and bounds in the world of physics and chemistry and there are things worth finding out about this scientist.

During the time he was studying under Neumann, he made the first of many outstanding research contributions that were related to electrical current. In 1845, he announced Kirchoff’s laws and they allowed the calculation of currents, voltages and resistances in electrical circuits that had multiple loops. This further extended German mathematician Georg Ohm’s work.

A couple of years later, Gustav Kirchoff’s work would lead to recognize this error and prod him to come up with a better and keener understanding of how the theory of electrostatics and electric currents could be and should be combined.

Kirchoff's Laws

It's two 'rules' that allow to study circuits in a systematic way. These rules are deducted directly from the field equations. To formulate the laws you need to define some of the concepts

Circuit: A conductive path, which are sources of 'Fem'. (batteries).

Knot or node: Points in a circuit in which at least three conductors are attached.

•Nodes Act: is the equation of continuity - permanent rule. "The algebraic sum of currents entering a node is always zero."

•Law of mesh: the 'fundamental relationship', in entire career in a circuit is closed, the algebraic sum of the'
