Teaching Electronics in Technical and Vocational Colleges

Labs take advantage of myDAQ and Multisim to help build and simulate rectifiers and transistor biasing circuits.
This set of labs is aimed at teaching introductory and advanced electronics concepts for engineering technology and technician programs. These materials provide you with 8 laboratories that use NI Multisim and NI myDAQ that can be easily integrated into your two-year or vocational program. Students are guided through labs focused on teaching the fundamentals of rectifiers, LED biasing, and LED IV characterization.

Students build circuits used to convert alternating current to pulsating direct current using semiconductor diodes for a simple half wave rectifier.
Students build a full wave bridge rectifier circuit used to convert alternating current to pulsating direct current.
Students build a full wave bridge rectifier circuit with a capacitor (called a filter capacitor) used to smooth out the pulsating direct current created by our rectifier circuit. We will observe how the size of the capacitor and load impedance affect the ripple voltage across the load (and current through it).
Students study the effects of frequency on the filtering of the pulsating direct current created with a rectifier.
Students experiment with simple resistor bias and the effect on current in a circuit when an LED is replaced with another LED of different color.
Students experiment with current stability through an LED using a voltage divider biased transistor circuit as a current source.
Students simulate and then construct a complete transistor based current source which will be used to drive an LED.
Students build a circuit that will allow you to perform IV (current versus voltage) curve tracing using the myDAQ module for LEDs and other semiconductor diodes. This circuit utilizes a discrete transistor voltage follower circuit to provide current amplification.


Multisim is a circuit simulation tool built for educators to teach analog, digital, and power electronics by connecting simulation to experimentation. 


Combines a comprehensive set of plug-and-play computer-based lab instruments with portability for hands-on student learning in or outside the lab.
