What This Document Is
This document is a lab manual excerpt for Electrical Circuits (EMT 1150) at New York City College of Technology, specifically for Lab 4 focusing on Ohm’s Law measurements. It provides foundational information and guidance for building and testing simple resistive circuits using a breadboard and power supply. The excerpt details the function and structure of breadboards, and introduces the power supply options available for the lab – a standard DC power supply and a 9V battery kit.
Why This Document Matters
This lab manual section is essential for students enrolled in EMT 1150 who are learning to apply Ohm’s Law practically. It’s used during the lab session to guide the construction of circuits and the accurate measurement of voltage and current. Understanding breadboard functionality and safe power supply usage are critical first steps in hands-on electronics work. This document exists to prepare students for successful experimentation and data collection.
Common Limitations or Challenges
This excerpt focuses on the *setup* for Ohm’s Law measurements. It does not provide the actual experimental procedures, data tables, analysis questions, or the full theoretical background of Ohm’s Law itself. Students will still need to understand the underlying principles of voltage, current, and resistance to successfully complete the lab. This preview does not cover troubleshooting techniques or advanced circuit configurations.
What This Document Provides
This document includes:
* A detailed explanation of breadboard construction and how to use it for prototyping circuits.
* Visual aids (Figures 4.1 and 4.2) illustrating breadboard structure and power supply options.
* A schematic and protoboard connection diagram for a simple resistive circuit with a switch.
* Guidance on connecting components on a breadboard, including the use of jumper wires.
This preview *does not* include the complete lab procedure, data collection instructions, calculations, or analysis questions. It focuses solely on the initial setup and component understanding.
