Exploring the Relationships between Voltage, Resistance, and Current: A Lab Report, Study Guides, Projects, Research of Electrical Circuit Analysis

City University of New York (CUNY) - Hunter CollegeElectrical Circuit Analysis

This lab report by sebastian broncano for ens 241 investigates the relationships between voltage, resistance, and current, using data from experiments conducted under the guidance of professor jorge guerrero. The report discusses the inverse proportional relationship between resistance and voltage, as well as the linear relationship between total resistance and voltage. The report also touches upon the impact of deviation and tolerance percentages on these relationships.

Introduction

The definition of resistance is best described as the electrical resistance of a substance in which it’s measure is the opposition to the flow of electric current. This resistance is measured in SI unit of Ohms ( Ω). Where current is expressed as the natural flow of the direction of electrons within circuit wiring in which current is measured in Amps (A). As such the Voltage is defined as Voltage describes the amount of energy measured in Volts (V) associated with electric charge as it moves around in a circuit. Ohm’s law constructs the relationship between both Current and

Voltage are directly proportional for a given resistance. This lab further explores the comparisons between the relationships of voltage, resistance and current as they undergo various changes.

Discussion

Problem 1

  1. It becomes evident based on the data recorded and the comparisons between Resistance and Voltage are best described as having an inversely proportional relationship which is further justified by Ohm’s law equation:

Based on the given graph the gradient demonstrates the natural log slope of the comparison between both the Voltage and the Resistance, this gradient is 3.8128 ln(x) =5.

  1. The impact between both the Deviation Percentage and the Tolerance Percentage defines the relationship with gradient as such this comparison demonstrates the fluctuating positive relationship. The gradient provides a fourth order polynomial which mostly like occurred because a technique issue, the function which best would describe this gradient is an exponential.

Problem 2

  1. Based on the given results provided by the analyst it becomes clear that each representation of the given values of Total Resistance defined in that circuit as well as the Voltages within these expressions. From this conclusion each gradient expresses a linear relationship as both values are directly proportional to each other. The Percent deviation describes a less than 1 percent providing useful data.
