CWI: Understanding Electrical Circuits and Drawings (ENG)

This class introduces the essential foundation of electrical drawings, which serve as vital tools for the design, documentation, and maintenance of electrical systems. These drawings provide graphical representations of components, connections, and configurations, allowing engineers,
technicians, and electricians to construct, interpret, and troubleshoot circuits effectively.

Electrical drawings are organized into four primary categories, each encompassing specialized technical diagrams tailored to specific applications. In this course, we will examine these categories in detail, exploring their purposes, defining features, and practical uses.

CWI: Understanding AC and DC Currents (ENG)

This class introduces the fundamentals of Direct Current (DC) voltages and currents, providing the groundwork for understanding DC electrical systems in both theory and practice.

DC Voltage:
Unlike alternating current (AC), which varies in a sinusoidal pattern, DC voltage remains constant over time. This stability makes it especially well-suited for powering electronic devices, battery-operated equipment, and other applications requiring reliable energy.

DC Current (DC):
DC current flows consistently in a single direction, offering predictable and stable performance.

In this course, we will examine how DC current is generated, measured, and controlled, as well as its relationship to voltage and resistance through Ohm’s Law.

Key Concepts Covered:
• Ohm’s Law: Understanding the relationship between voltage, current, and resistance
• Kirchhoff’s Laws: Techniques for analyzing complex DC circuits
• Power in DC Circuits: Methods for calculating power dissipation and efficiency
• Series and Parallel Circuits: How components behave in different configurations

• Practical Applications: Real-world uses of DC systems, from power supplies to modern electronics

By the end of this class, you will have the ability to analyze and design DC circuits, applying these principles to a wide range of industrial and technological contexts.

CWI: Electrical Safety in the Workplace (ENG)

Your participation in this class reflects a proactive commitment to workplace safety—an essential foundation for our collective well-being. The knowledge and skills you develop here will serve you throughout your career.

Safety is not a single achievement; it is a continuous practice that demands awareness, responsibility, and collaboration. A truly productive and positive work environment begins with prioritizing safety. Whether you are just entering the field or bringing years of experience, safety is more than a checklist of rules—it is a lasting dedication to creating a workplace where everyone feels protected and respected.

In this class, we will explore:

• The significance of safety in every aspect of work
• Core principles of risk management
• The critical role of communication and training
• Practical methods for identifying and mitigating potential hazards

CAC: Understanding Electrical Power (ENG)

This class covers Alternating Current (AC) which is the most widely used form of electrical power in residential, commercial, and industrial applications worldwide. Unlike Direct Current (DC), where charge flows in one constant direction, AC periodically reverses direction.

Why AC Matters: AC power is the backbone of modern electrical systems, providing energy for households, industries, and businesses. Its versatility, efficiency, and ease of transmission make it the dominant form of electrical generation and distribution globally.

This class provides an in-depth analysis of AC power sources, covering:

  • Principles of AC generation.
  • Transmission methods.
  • Applications in everyday life.
  • Advantages that make AC the preferred choice for energy distribution.

CAC: Electrical Mastering Ohm’s Law (ENG)

In today’s technology-driven world, a solid grasp of electrical principles is essential for careers in engineering, electronics, and applied physics. This course on Ohm’s Law provides a critical foundation, offering a clear and structured exploration of the relationship between voltage, current, and resistance in electrical circuits.

Through the study of Ohm’s Law, participants will develop both strong analytical skills for troubleshooting and designing circuits, as well as a deeper understanding of how electrical systems function and interact.

Definition:
First introduced in the 1820s by German physicist Georg Simon Ohm, Ohm’s Law defines the relationship between voltage, current, and resistance. It remains a cornerstone of electrical engineering and physics, bridging theoretical concepts with practical applications in modern electronics.

CAC: Understanding National Electrical Code (ENG)

The National Electrical Code (NEC), formally known as NFPA 70, stands as a cornerstone of electrical safety in the United States and beyond. Created by the National Fire Protection Association (NFPA), the NEC establishes standards for the safe design, installation, and inspection of electrical systems.

Since its introduction in 1897, the NEC has grown into a globally recognized framework, widely adopted across the U.S. and referenced internationally. Despite its prominence, misconceptions remain—some view it as a law, a design manual, or a one-size-fits-all solution. In reality, the NEC is a flexible set of standards designed to guide safe and effective practices.

This class provides a clear understanding of the NEC’s purpose, structure, and application, while dispelling common misunderstandings about its role in electrical engineering and construction.
