his course provides the fundamental electrical knowledge needed to understand controls and the use of electrical circuit drawings.

Upon completing of this course, you will be able to: 

• Understand the mathematical relationships between power, voltage, current, and resistance (Ohm’s Law and Power Law)
• Understanding the importance of capacitance, inductance, power factor
• Comprehend the uses and functions of relays
• Examine how transformers work and why they are used in power services and control systems
• Determine how the motor starter functions
• Identify the advantages of variable speed drives for fans
• Become familiar with Boolean logic, and relay logic using electrical circuit drawings (ladder diagrams)
