Videos: Lab Concepts for DC Electricity

Seneca College has some great technologist programs in the School of Information and Computer Technology. Most students in an ICT program are required to take a common first semester course called ETY155, also known as “DC Electricity”, which is one of the core courses for the year. The course covers topics like Ohm’s Law, Series and Parallel resistors, circuit analysis methods, and the charging rate of capacitors.

Since the course has both a lecture portion and a lab portion, instructors typically give out lab work every week and the students hand in their assignments after completing their work. One of their labs this semester was to work together in groups of two or three to produce a video on one of the topics we had learned in the previous section of labs. (They could then use the videos as resources to study for their upcoming lab test.)

The following films were all produced by first semester Seneca students.

Lab Safety Rules & Main Stations          Unlisted. 2.5 mins.

All students must follow certain rules while present in any Seneca lab. This video humorously depicts some of them, including showing the power to the lab and the Safety Station (surrounded by green-and-white stripes).

 

Lab Station Equipment         Unlisted. 6.5 mins.

This video takes us inside a Seneca lab to a typical first-semester lab station. These students enthusiastically introduce the viewer to each of the equipment we will get to use in the lab.

 

Introduction to a Breadboard          Unlisted. 3.5 mins.

Students use breadboards throughout the semester to build a variety of circuits and to take measurements from. This video colourfully illustrates how one is wired and shows how to use it with simple circuits.

 

Introduction to a Digital Multimeter (DMM)          Unlisted. 4 mins.

This video demonstrates the variety of functions available on Seneca’s DMMs, such as the DC voltmeter, DC ammeter, and Ohmmeter, as well as the functions that will be used in later semesters.

 

Introduction to a DC Power Supply          Unlisted. 4 mins.

This video demonstrates the use of a typical analog DC Power Supply, namely the constant voltage source. (Some labs are equipped with digital.) Later in the course, students also learn how to use the constant current source.

 

Introduction to Series Circuits          Unlisted. 1.5 mins.

Learn how to construct a simple series circuit on a breadboard while watching this video. Simple hook-ups to the other lab equipment are also demonstrated.

 

Introduction to Parallel Circuits          Unlisted. 3 mins.

Learn how to construct a simple parallel circuit on a breadboard while watching this video. Simple hook-ups to the other lab equipment are also demonstrated.

 

Introduction to a Function Generator          Unlisted. 3 mins.

This video demonstrates the variety of functions available on Seneca’s Function Generators. (FGs are not typically used by students until the later semesters, which may explain some of the comments.)
