Investigating Basic Circuits

Introduction What is an electrical circuit? How can you manipulate components and design a circuit that will do what you want it to? This guided activity will introduce you to some components, tools, and concepts that are fundamental in electronics. It will allow you to investigate and discover: What are voltage, current, and resistance? How are they related to one another? What are some of the basic components that make up simple circuits and what do they do? What are the important characteristics of a circuit and how do I measure different parts of a circuit? How do I measure voltage in a circuit? How does the arrangement of components affect the characteristics of the circuit? How do I work…

How the Length of a Wire Affects its Resistance

In my physics coursework I am going to investigate the effect of the length of a wire on its resistance. Resistance is the measure of how easy it is for current to flow through a wire. Current is the rate of flow of charge through a conductor, and it is measured in amps using an ammeter. To help me plan my investigation I have completed a preliminary experiment in which I investigated the effect of the thickness of a wire on its resistance, using three constantan wires and one copper wire. I found that the resistance increased as the thickness of the wire decreased, however, when I did the test with the copper wire I found that it was so…
