Introduction to Marine Electrical is an introductory course to electrical engineering principles upon which the world of electrical and electronics applications is built on. Without this fundamental knowledge, it will be difficult for learners to comprehend marine electrical and electronic equipment on board. This basic knowledge will also help students remain safe in an environment where accidents due to electrocution are common. The concept of the battery is the basic building block of the electrical circuitry. A battery is a device consisting of one or more electrochemical cells with external connections for powering electrical devices such as flashlights, mobile phones, and even electric cars. When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal to complete the circuit. For controlling electrical equipment, an uninterrupted power supply is needed but such supply is impossible without any dynamic electrical generating machinery. Hence, a battery is used as the electric power in a battery which is continuously available in the form of a storage system.

Introduction to Marine Electricals is a free online course that graces marine electrical enthusiasts with the knowledge of fundamental principles of electrical components, standard symbols, and units. This course also outlines the relevance of these components to the standardized uniformity of global measurement of quantities and the derivation of units. The course will teach the graphical representation of different standard symbols used in electrical circuits. The concepts of electromotive force, current, potential energy, electrons, along with the effects of their movements in creating energy in electrical systems will also be analyzed in this course. The course also analyzes potential difference as a fundamental aspect of electricity and electronics. It illustrates how EMF and PD are indicated by arrows from the source and toward the direction of conventional current flow. You will also learn about the unit of Electromotive Force and Potential Difference as well as the representation of resistance, voltage, current, and power on a chart for reference. Also, a different formula for calculating values of electricity quantities including the definition of terminologies and associated technologies will be studied in this course.

Lastly, this course aims to equip learners with the basic knowledge of marine electrical consisting of an analysis of resistance and resistivity from their units, including the factors that affect them. You will also learn about the classification of materials based on their values of resistivities. This course will teach inductance from its measurement unit and the relevance of electric current in creating a magnetic field when passed through a coil. You will study capacitance from its measurement unit, capacitors, as well as the factors affecting the capacitance of a capacitor and the color-coding for capacitors. You will also learn about the distinction between ideal/independent voltage sources and dependent voltage sources as well as that of passive and active elements in electrical circuits. You will study different network elements in electricity covering the similarities and differences between bilateral and unilateral networks, linear and non-linear networks, along with lumped and distributed networks. You will also examine different materials from their physical properties and characteristics relating to the flow of electricity on an atomic level, along with the flow of electricity. You will learn about non-linear resistors including diodes, thermistors, and varistors as well as the instruments used for measuring resistance including the Wheatstone Bridge and the Slide Wire Bridge. The course will be of significant interest to students, researchers, marine engineers, and anyone seeking to learn about marine electricals.
