BDTU L1 Ohms Law

What is electricity — really? In this Core Lesson, we strip electricity down to what matters in the field: • What voltage actually does • What resistance really means • Why current behaves the way it does Using plain language and real-world thinking, this lesson introduces Ohm’s Law without math overload or textbook theory. No lab coats. No gimmicks. Just the fundamentals every technician needs to understand what’s happening in the circuit. This is not test prep. This is not engineering theory. This is how technicians should think about electricity. Core idea: Voltage pushes. Resistance limits. Current responds.
