Electrical Physics for Marine Engineers.

Course Title: Electrical Physics for Marine Engineers

Course Description: The Electrical Physics for Marine Engineers course is designed to provide marine engineers with a solid foundation in electrical physics principles and their application in marine electrical systems.

This course has been developed by Craig Miles, who used to train ETO’s and Cadets in electrical installation and maintenance, at South Shields Marine School.

This course will cover the fundamental concepts of electrical physics, including voltage, current, resistance, power, and electrical circuits.

Participants will learn about Ohm’s Law, electrical components, circuit analysis techniques, and the principles underlying marine electrical systems.

Practical examples and hands-on exercises will enhance participants’ understanding of electrical physics in the context of marine engineering.
