Lab # 1: Series and Parallel Resistor Circuits MNTC 208-001 Jordan Moffitt Lab time: 10am Performed: 10/7/23 Due: 10/12/23 Submitted: 10/28/23 .. Abstract Background: Resistors are the simplest electrical components when it comes to circuits. For such a tiny wire it can produce so much voltage. Purpose: The purpose of this lab is to look at different parallel circuit designs and see how each ones reading differs based on the design and how many resistors are on that design, plus the power source. Design/Method: Breadboard full of resistors arranged into combinations of parallel circuits. Results: The results will be inserted below. Conclusions: Making sure the voltage current of the 9V battery is important to getting the right reading with the DMM. Plus holding the switch is important. 1 MNTC 208-001 Lab 1 Fall 2023

As we continue to develop in the world that is going deeper into technology electricity demand is on high rise. Electricity has been such an intricate part of our lives since its discovery. It has helped humans evolve more and better over time. In this class and lab, we get to see the importance of electricity up close, and it is very intriguing on how it works and flows. Continuing in the Resistors in series and parallel circuits are connected when the same current flows throughout all the resistors. Connected in parallel when the same voltage is across all the resistors. Procedure For this lab the items needed are a Breadboard, Resistors, DDM, Battery, Switch, Jumper wires and Multism. The student or conductor will insert the correct resistors into sections of a bread board. Then for each resistor Jumper wires will be attached and following the current to the switch, which is attached to the battery, then holding down the switch the Multimeter (DDM) will have its reading. This procedure will be done for both voltage and current and data will be recorded onto the data sheet. 3 MNTC 208-001 Lab 1 Fall 2023

Results Discussion Combination circuits that comprised of 15k, 5.6k, 3.9k, 220, and 68 k resistors. The readings for each resistor, done by the multimeter and switch being held down, matched the calculations that were done beforehand by Dividing the designated resistor by the 9V battery. Conclusions So, in this lab we performed tests on resistors and measured each of their voltage and current. And the troubles that were presented were power going through the jumper cables to the switch, due to the misplacement of a resistor, switch or a dead battery. But with proper 4 MNTC 208-001 Lab 1 Fall 2023
