Electronics Repair Technician

Electronics Repair Technician


Modern life is powered by electricity, but electrical equipment sometimes breaks down. Electronics repair technicians can troubleshoot a piece of malfunctioning equipment and repair it. They can also test and maintain equipment to keep it from breaking down at all.

"Electronics" is a broad category, and electronics repair technicians find jobs in a number of settings and can pursue any range of specializations, including heating and air conditioning, home appliances, computers, and telecommunications, among others. Some electronics repair technicians even specialize in musical instruments such as electric guitars. While handson experience is important, most electronics repair technicians find that entry and advancement in the job market are easier if they have a strong math and science background in high school from classes such as physics, algebra, trigonometry, and calculus. It is also helpful to have a two-year degree in electronics technology from a community college or vocationaltechnical college. Such a program emphasizes not only electronics, but also applied mathematics and geometry. Although it is not mandatory, many pass an exam to be become certified.

Good electronics repair technicians have a firm grasp of the mathematics and physics of electricity. They have to measure and understand electrical charges, currents and amps, voltage, and resistance. They must be familiar with Ohm's law, which is the relationship between current, voltage, and resistance. An electronic repair technician should understand the structure and operation of electrical components, including resistors, capacitors, diodes, transistors, integrated circuits, and switches. In addition, they need to read and understand schematic diagrams , which visually present "outlines" of circuits, showing how electrical components connect.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
