Subject Title
Electricity

Subject Description
This subject covers all the fundamental elements of electricity in both a lecture and lab setting. Students acquire an understanding of electrical principles and are able to systematically troubleshoot electrical ac and dc circuits while learning the purpose of resistance, conductors and power supplies found in various circuits and electrical construction. In order to accomplish this, students must have a practical working knowledge of a digital multi-meter. Multi-meters are used extensively in the labs.

This subject also familiarizes students with proper safety procedures as they relate to the Canadian Electrical Code. Students are required to follow all safety rules and regulations when working in the labs.

Credit Status
One credit toward the Fire Protection Technician or Fire Protection Engineering Technology Diploma and the Fire Alarm Technician programs.

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. demonstrate and discuss basic personal electrical safety and lockout procedures;
2. identify on a drawing and have a clear practical understanding of and correct use of the following terms and components:
Resistors, Conductors, Insulators
Batteries, Lamps, Switches
Wires & Cables, Fuses, Breakers
Power Supplies AWG3;
3. describe and correctly use units of electric charge, current, voltage, resistance, energy and power and use metric engineering prefixes to express answers;
4. apply the resistor colour code to determine resistance and tolerance;
5. correctly measure current, voltage, and resistance by using a digital multi-meter;
6. apply Ohm's law, calculate and measure the current, voltage and resistance in simple dc resistive circuits;
7. apply Watt's law to calculate power in simple dc resistive circuits;
8. apply Kirchhoff's voltage and current laws to voltage and current dividers in series and parallel dc resistive circuits;
9. analyze series-parallel dc resistive circuits;
10. troubleshoot simple dc resistive circuits;
11. discuss AC circuits, RMS, peak to peak and average current.

Cheating and Plagiarism
Each student should be aware of the College's policy regarding Cheating and Plagiarism. Seneca's Academic Policy will be strictly enforced.

To support academic honesty at Seneca College, all work submitted by students may be reviewed for authenticity and originality, utilizing software tools and third party services.
