Matt Weiner Phys. 241 Lab Lab Partner: Phillip Hoffman 9/12/06 Introduction to Electrical Circuits and Meters Goal: The goal is to gain some familiarity with electrical circuits and the instrumentation used to make electrical measurements. Theory: To measure Voltage between two points on connects each of the two points of interest to one of the terminals of a voltmeter. To measure electrical Current one must insert an ammeter into the circuit at the point of interest. To characterize how an element restricts the flow of electrical charge, one might apply a standard voltage across the device and measure the electrical current flow. The ratio of applied voltage to the current flow is the Resistance . Components are usually connected in series of in parallel to form a subassembly as shown in fig. 1 below. For components in series, the same amount of current flows through each component, while for parallel components, the current flowing into the circuit is divided between the parallel branches.
