Electrician's Mate
Electrician's Mate (abbreviated as EM) is a United States Navy and United States Coast Guard occupational rating. The Electrician's Mate's NOS is B210. History The Navy Electrician rating was established in 1883, then promptly disestablished in 1884, only to be re-established as a Navy rating in 1898. The Electrician rating changed to its current name, Electrician's Mate, in 1921. Duties Electrician's Mates stand watch on generators, switchboards, control equipment and electrical equipment; operate and perform organizational and intermediate maintenance on power and lighting circuits, electrical fixtures, motors, generators, voltage and frequency regulators, controllers, distribution switchboards and other electrical equipment; test for short circuits, ground or other casualties; and rebuild electrical equipment, including solid state circuitry elements, in an electrical shop. Requirements A pre-qualified and selected group of Electrician's Mates attend the Naval Nuclear P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Short Circuit
A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes. Definition A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion. Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protectors. In circuit analysis, a ''short circuit'' is defined as a connection between two nodes that forces them to be at the same voltage. In an 'ideal' ...

List Of United States Navy Ratings
United States Navy ratings are general Enlisted rank, enlisted Job (role), occupations used by the United States Navy, U.S. Navy since the 18th century, which denote the specific skills and abilities of the sailor. Each naval rating has its own specialty badge, which is worn on the left sleeve of dress uniforms of enlisted rank, enlisted personnel. U.S. naval ratings are the equivalent of United States military occupation code, military occupational specialty codes (MOS codes) used by the United States Army and the United States Marine Corps, the List of United States Coast Guard ratings, ratings system used by the United States Coast Guard, and Air Force Specialty Codes (AFSC) used by the United States Air Force and United States Space Force. Ratings should not be confused with ''List of United States Navy enlisted rates, rates'', which describe the United States Navy, Navy's enlisted rank and pay-grades.

List Of United States Coast Guard Ratings
The United States Coast Guard's ratings are general occupations that consist of specific skills and abilities. Each rating has its own specialty badge, which is typically worn on the left sleeve of their service dress uniform by enlisted personnel in that particular field. On operational dress uniforms, they wear generic rate designators that exclude the rating symbol. Commissioned officers do not have ratings. U.S. Coast Guard ratings are the equivalent of the rating system used by the United States Navy, known as Navy Enlistment Classification (NEC) codes. The United States Army and United States Marine Corps use Military Occupational Specialty (MOS) codes and the United States Air Force use Air Force Specialty Codes (AFSC) that service the same function as U.S. Coast Guard and U.S. Navy ratings. Ratings should not be confused with " rates", which describe the Navy's and Coast Guard's enlisted pay-grades. Enlisted Navy and Coast Guardsmen are referred to by their rating and ra ...

Armed Services Vocational Aptitude Battery
The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple choice test, administered by the United States Military Entrance Processing Command, used to determine qualification for enlistment in the United States Armed Forces. It is often offered to U.S. high school students when they are in the 10th, 11th and 12th grade, though anyone eligible for enlistment may take it. History The ASVAB was first introduced in 1968 and was adopted by all branches of the military in 1976. It underwent a major revision in 2002. In 2004, the test's percentile rank scoring system was renormalized, to ensure that a score of 50% really did represent doing better than exactly 50% of the test takers. Categories Format The ASVAB contains nine sections and takes three hours to complete. The duration of each section varies between 7 and 39 minutes, the longest being for Arithmetic Reasoning. The test is typically administered in a computerized format at Military Entrance Processing Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Power School
Nuclear Power School (NPS) is a technical school operated by the U.S. Navy in Goose Creek, South Carolina as a central part of a program that trains enlisted sailors, officers, KAPL civilians and Bettis civilians for shipboard nuclear power plant operation and maintenance of surface ships and submarines in the U.S. nuclear navy. As of 2020 the United States Navy operates 98 nuclear power plants, including 71 submarines (each with one reactor), 11 aircraft carriers (each with two reactors), and three Moored Training Ships (MTS) and two land-based training plants. NPS is the centerpiece of the training pipeline for U.S. Navy nuclear operators.

Solid State (electronics)
Solid-state electronics means semiconductor electronics: electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD) a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk. History The term "solid-state" became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology based on the transistor, in which the electronic action of devices occurred in a solid state, from previous electronic equipment that used vacuum tubes, in which the electronic action occurred in a gaseous state. A semiconductor device works by controlling an electric current c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voltage Regulator
A voltage regulator is a system designed to automatically maintain a constant voltage. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages. Electronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements. In automobile alternators and central power station generator plants, voltage regulators control the output of the plant. In an electric power distribution system, voltage regulators may be installed at a substation or along distribution lines so that all customers receive steady voltage independent of how much power is drawn from the line. Electronic voltage regulators A simple voltage/current regulator can be made from a resistor in series with a diode (or series of diodes). Due to the loga ...
