In order to correctly set up the breadboard, the ululations were used to determine which set of resistors needed to be matched together. Each color on the resistor represents the resistors value. The first and second bands represent the first two digits of the resistor value, the third band represents the multiplier, and the fourth band is the tolerance. After adding up the total resistor values, it is significant to match up the resistors to create a total of the calculated result of voltage drops between nodes.
A schematic that illustrates my breadboard was done through Microsoft Vision and included in my Electrical Design Package. The breadboard was tested in class through he use of a voltmeter and a battery. The outcome of this project provides an understanding that the calculations play a significant role in the accuracy of the overall result of success. If the calculations were accurate, the result will be successful.
However, if the calculations demonstrated a significantly large difference between the work done and the result of the voltage through the breadboard testing, the project results in a failed outcome.
Sincerely, Rona Bullhead 1201 engineer student Electrical Circuit Project Lab Report Prepared for: SLIM Engineering Design Firm ANGER 1201-002 Prepared by: Date submitted: 2/17/15 have neither given nor received any unauthorized help on this assignment, nor witnessed any violation of the UNC Charlotte Code of Academic Integrity. Introduction The Electrical Circuit Project provides a purpose of working with electrical circuits and using calculations to create successful circuits.
The project aims to inform students with knowledge on voltage dividers, designing processes, and calculations.
Design requirements To calculate the voltage drops between each nodes and figure out the equivalent resistance in order to create a successful breadboard. An accuracy in calculations exults in a successful result of testing the breadboards. To demonstrate a successful result of the tested breadboards through the use of correct and accurate calculations. Constraints The project must include a combination of parallel and series resistor configurations. A combination of the two gives a better understanding of how to calculate resistor configurations in any problem.
A problem can include parallel circuits alone, series circuits alone, or a combination of the two. Certain resistors are provided in class. Only those resistors can be used. The resistors used for this project will need to have a tolerance of В± 5%. Assumptions By the end of this project, students will have the ability to work with various methods to work through a design process. Students will have a better understanding of how to use calculations to work through electrical circuits. Reading resistor values will be understood after this project.
Background A reliable website source provided me with various information needed for this project. Through this source, I was able to see the many calculations useful for this project. Including the voltage divider equation: , which aids in finding the output voltage. Also, research was conducted in order to evaluate the total aloes for each resistor through the use of the color chart that determines the resistor’s values. Through my research, I found that the first and second bands represent the first two digits of the resistor value, the third band represents the multiplier, and the fourth band is the tolerance.

Resistor Color Codes “4 Band Resistor Color Codes” Other equations needed to create a successful result for this project includes the Ohm’s law equation to calculate the voltage drops and ARQ, potential difference to calculate the differences between voltage nodes, calculations of resistors in really and resistors in series to obtain results of an accurate total of resistors. The calculations are as follows: Ohm’s law: V=IR Potential difference: VI -VI Resistors in parallel: 1/ARQ Methods and procedures = I/RI +1/RE+ 1/RE +.. ..
