Electrical Principles for Safety Professionals
ASP written lesson, 9 min read. ASP Domain 2: Safety Programs and Concepts
Written with AI help from the rules it covers, then fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.
What you'll learn
- Define voltage, current, resistance and impedance and give their units
- Solve Ohm's law and power problems for an unknown value
- Convert power and time to energy in kilowatt-hours
- Calculate total resistance for series and parallel circuits
- Explain how body resistance and current path affect shock severity
What this lesson covers
This lesson covers the electrical basics the Associate Safety Professional (ASP) exam expects: voltage, current, resistance, Ohm's law, power, energy, impedance, and series and parallel circuits. It ties each one to a shock, burn or fire hazard. It matters because current, not voltage alone, injures people, and the same math explains why wet skin and overloaded cords are dangerous.
This lesson is included with a pass
