In this lesson we will present the concept of “junction" and “loop” of an electrical circuit. We will present the Kirchhoff's Laws, the 1st Law and the 2nd Law, whose expressions will be used, along with the typical relations of the elements, in order to determine the different voltages and currents from the circuit (see, Linear Circuits). Relying on Kirchhoff's Laws, we will define the series connection and parallel conneciton of two dipoles.
