Current

In this lab, students will learn about the concept and properties of current. Students will simulate circuits with ideal voltage and current sources and experiment using Ohm’s law to understand how current is derived from known voltages and resistances. Finally, students investigate Kirchoff’s Current law and the result of having multiple current pathways.

This is lab 5 of 17 in the course, Measurements and Instrumentation.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Measure electric current using the NI ELVIS III DMM
  2. Use the Automated Measurement Application Board current measurement circuit to measure a variable current and display its change over time on your screen using LabVIEW
  3. Explore the behavior of current through resistors that are connected in parallel to Voltage source
  4. Explore the behavior of current through resistors that are connected in series to Voltage source
  5. Use Multisim Live to experiment with voltage across loads connected to a constant current source
  6. Use Multisim Live to experiment with current flow through loads connected to a constant voltage source
 

REQUIRED SKILLS

 
  • Basic proficiency using Multisim Live and LabVIEW
  • Basic proficiency using ELVIS III Instruments
  • Basic knowledge of components and their behaviors

NI ELVIS III

Engineering laboratory solution for project-based learning that combines instrumentation and embedded design with a web-driven experience, delivering a greater understanding of engineering fundamentals and system design.

LabVIEW

LabVIEW is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data insights.

Multisim Live

Multisim Live is an online, touch-optimized component of Multisim, so students can design and simulate their circuits anywhere, anytime, on any device.

Automated Measurements Board for NI ELVIS III

An application board for NI ELVIS III that provides students with a experimental platform for understanding and designing a signal chain for sensor integration.
