Electricians primarily use amperes, or amps (A), to measure electrical current, which is the rate of flow of electric charge. Voltage, measured in volts (V), represents the electrical potential difference, and resistance, measured in ohms (Ω), quantifies how much a material opposes the flow of current. Understanding the relationship between these three, governed by Ohm's Law (V=IR), is fundamental for diagnosing and resolving electrical issues in San Diego properties. These units are critical for calculating load capacities and ensuring system safety.
