Unformatted text preview: Kirchoff's Laws German physicist Gustav Robert Kirchhoff, developed two laws for electrical circuits, they are known as Kirchhoff's Laws of Networks. The first of Kirchhoff's laws states that at any junction in a circuit through which a steady current is flowing, the sum of the currents flowing to the point is equal to the sum of the currents flowing away from that point. In automotive terms, the current leaving the automobile positive battery terminal is equal to the current entering the negative battery terminal. In the circuit below, 2A of current leave the 12V source and 2A comes back into the 12V source ground. The second law states that, starting at any point in a network and following any closed path back to the starting point, the net sum of the electromotive forces encountered will be equal to the net sum of the products of the resistances encountered and the currents flowing through them. In automotive terms, this means that all of the battery voltage is dropped (or used up), in every single...
