Investigation into resistance of a wire (contains spaces for diagrams).

Coursework An Investigation Into The Resistance of different lengths of wire Intro <Tab/>In my coursework I intend to determine the relationship between resistance of a circuit and the length of a piece of wire. Planning Planning 1: Preliminary Work: I performed preliminary work to evaluate what voltage I was going to use for my proper experiment. The apparatus I will use for the preliminary is the same as I intend to …
