Investigating the E.m.f and Internal Resistance of 2 cells on different circuit Structures Background Knowledge: For this investigation the main variable will be the circuit structure and positioning of the two cells. Therefore I will discuss in brief the most relevant aspects of the electricity module regarding this investigation. These are the electrical circuits, the electromotive force and the internal resistance. Circuits: According to Kirchoff's first law, the series circuit is one in which the components are connected one after another, forming one complete loop. Diag1: The next circuit I will also be using is the parallel circuit. I am using these two circuits because the main aim from this investigation is see how the two circuits influence the e.m.f and the internal resistance. The parallel circuit is one where the current can take alternative routes in different loops. The current divides at a junction, but the current entering the junction is the same...
