Basic Electricity and Circuit Fundamentals
A practical foundation in electrical principles for beginners and non-electrical personnel. This course covers core concepts, basic Ohm's Law calculations, component identification, and essential safety and troubleshooting practices.
Introduction to Electricity Define electricity at a high, conceptual level. Explain the difference between static and current electricity. Voltage, Current, and Resistance Define the terms voltage, current, and resistance. Identify the standard units of measurement for each (Volts, Amps, Ohms). Types of Current: AC vs. DC Differentiate between Alternating Current (AC) and Direct Current (DC). Identify common real-world power sources for both AC and DC. Anatomy of a Circuit Identify the three required elements of a basic electrical circuit: power source, load, and conductive path. Explain the difference between an open circuit, a closed circuit, and a short circuit. Ohm's Law Fundamentals State the formula for Ohm's Law. Explain the proportional relationships between voltage, current, and resistance. Calculating Circuit Behavior Apply Ohm's Law to calculate unknown voltage, current, or resistance values in simple DC circuits. Predict how changing one electrical property will affect the others in a live circuit. Common Electrical Components Identify the physical appearance and schematic symbols of basic components. Describe the basic functions of resistors, capacitors, and switches. Series and Parallel Circuits Differentiate between series and parallel circuit configurations. Explain how voltage and current behave differently in series versus parallel setups. Practical Circuit Applications Analyze how switches control loads in practical applications. Recognize the basic layout of common household and industrial circuits. Electrical Hazards and Safety Practices Recognize common electrical hazards in residential and industrial environments. Explain the physiological effects of electric shock and how to prevent it. Lockout/Tagout (LOTO) Concepts Define the purpose and importance of Lockout/Tagout (LOTO) procedures. Outline the basic steps for safely de-energizing and verifying equipment is safe to work on. Using a Multimeter Identify the main functions and settings of a standard digital multimeter. Demonstrate the basic steps to safely measure voltage, current, and continuity/resistance.
