  18. \section{Introduction and Objective}
  19. Lab 1 primarily deals with acquainting the student with common lab items. The lab specifically focuses on resistors, solder-less breadboards, and extensive use of the multimeter. The portion of the lab that deals with resistors introduces the color code standard that appears on all of them. The difference between theoretical resistance and actual resistance is also calculated in this lab. The solder-less breadboard provides a platform to test circuits. The digital multimeter consists of a ohmmeter, voltmeter, and ammeter. They measure the resistance, voltage, and current, respectively, along the two leads that extend out of the multimeter.

  21. \section{Preliminary Design}
  22. The first portion of the pre-lab is Table 1-4. It lists the nominal values for the resistors provided in this lab. The next column asks for the color code of the respective resistor. This is accomplished by writing the color codes as dictated by Table 1-2 in the lab. The next column asks for measured resistance, i.e. the reading off the digital multimeter. The final column is percent error between the measured value and nominal value. The last half of the pre-lab is Table 1-5. It displays various resistance configurations in the first column, such as: two resistors in series, two in parallel, and various combinations of both. The second column provides a formula to determine the total resistance of the circuit given in the first column in that row. The third column provides nominal values for the resistors. The fourth column asks for the calculation of total resistance of the circuit given in that row based on the nominal values. The fifth column ask for the same calculation, but done with measured resistance. The final section asks for the measured resistance of the circuit as it was set up on the breadboard.

  24. \section{Experimental Procedure and Data}
  25. The first portion of the lab is setting up the power supply with the bench digital multimeter (DMM). Table 1 is the recorded voltage readings when the leads were directed to that in the right column.
