ETA CETa study guide

ETA CETa · Work through your exam, one topic at a time.

The Associate Certified Electronics Technician (CETa) is ETA International's foundational electronics credential, aimed at people entering the field or formalizing basic electronics knowledge - students in electronics programs, apprentices, military technicians, and career changers. It sits at the base of ETA's certification pathway: ETA lists CETa as the foundation-level credential in its DAS Master Specialty sequence, where it can be satisfied by CETa or General Communications Technician – Level 1 (GCT1). ETA describes CETa as a "basic electronics" certification and publishes an in-house study guide for it, written by industry professionals and featuring chapter quizzes and practice exams; ETA members receive a discount on that guide, and bulk discounts are available. Because certification questions are derived from each certification's published competency, the free competency document is the authoritative statement of what the exam covers and the best place to start planning study. ETA certifications are vendor-neutral and accredited by the International Certification Accreditation Council (ICAC), and ETA states that membership is not required to take an ETA examination. Exams are delivered through Trapeza, ETA's online testing system, or on paper, with a Certification Administrator present either way. Topics on this exam: Basic Electronics. The ETA CETa study guide has 1 section and about 443 words.

Basic Electronics

Basic Electronics is the foundation domain of the ETA CETa exam. It checks whether you can apply DC and AC fundamentals, passive-component behavior, circuit laws, and correct meter use to simple circuits, rather than memorized pinouts or advanced troubleshooting. Current is charge flow; voltage is potential difference; resistance opposes current. Conventional current flows from positive to negative, opposite electron drift.

  • Study planDefine voltage, current, resistance, and power and state the unit and symbol for each.
  • Common mistakesCandidates memorize V = IR as a universal rule and forget that a forward-biased diode has an approximately constant voltage drop (about 0.7 V for silicon, 0.3 V for germanium) that must be subtracted from the supply before dividing the remaining voltage by the series resistance.
