Ohm’s Law in Pipeline Cathodic Protection and Circuit Analysis
The practical application of Ohm’s Law in pipeline cathodic protection systems and electrical circuit analysis. Key topics include the linear relationship between voltage (E), current (I), and resistance (R), and how Ohm’s Law is used to measure polarization and depolarization in rectifiers during "instant off" and "instant on" scenarios. The video further explains the importance of current flow direction—conventional versus electron flow—and how to measure current using an ammeter or a shunt without interrupting the circuit. This essential knowledge helps professionals accurately assess current, voltage drops, and maintain pipeline integrity using effective cathodic protection techniques.
