To Intro Circuits and Meters By Alex Chambers Lab Preformed: 2 September 2008 Report Submitted: 9 September 2008 Goals: The goal of this lab was to gain basic knowledge and experience with circuits and equipment used in the laboratory. Data was taken for resistance, voltage, and current to understand circuits and how to quantify them. Theory: Electrical circuits are comprised of separate components such as batteries, wires, switches, resistors, and light bulbs. The battery is a supply of energy or power, the wires are the path and carrier of the energy to the other components of the system. Along the wires, resistors restrict the flow of power in the system. Using a DMM, the components can be quantified in (volts, resistance, and amps). Procedure: Part I: Various batteries of different power output are set out at the lab. Using the DMM, measure the amps produced by each battery. Parts II: A board with various sized and rating resistors are set out at the lab. Using the DMM, measure the resistance in ohms of each resistor. Part III: Using the circuit described in #14, quantify the components of the circuit. 1. Using the DMM measure the voltage between the sequential points in the circuit. Wire DMM in parallel. 2. Using the DMM measure the resistance in ohms between sequential points in the circuit. Wire the DMM in series. 3. Using the DMM measure the current between the sequential points in the circuit. Wire the DMM in series. Calculations: In this lab, the DMM takes readings by using its sensors and processor to do mathematical computations. Based on the equation V = IR The DMM makes of readings 2 variables to quantify the 3rd. Voltage by the flow of current I over a known resistor. Current by a flow of voltage through a known resistor. Resistance by a flow known current and its voltage. Results: From the data collected, predictable patterns emerged where expected. Voltage readings were highest and fairly consistent between the light bulbs that are resistors emitting heat and light. Current was fairly consistent through out the system with little variation, more could be contributed to time the battery spent on than to loss inside the closed system. Resistance was built up from the only two resistors in the system, the light bulbs, and grew as more light bulbs were added to the system as expected. The qualitative assessment of data of this lab would confirm the general theory of the mathematical models for the circuit system. Small derivations of mathematically expected constants could be attributed to the imperfection of the system and loss of power and also the age of the batteries used in the system. A chemical reaction is required in the batteries to run the circuit and age of the batteries time used could have depleted the reagents in the battery giving erratic power outputs. Conclusion: The theoretical models of circuits and electricity can easily be qualitatively performed in the laboratory. The real world imperfection of the system and loss to the out environment and dependence to a chemical reaction to pose as positional for error, but can easily be accounted for. The DMM is a useful tool for data collection in labs involving electricity and circuitry.
