On the CAT-ASVAB, Electronics Information has 15 scored questions with a 9-minute time limit. The paper-and-pencil version has 20 questions in 9 minutes. EI tests your knowledge of electrical principles, circuits, and electronic components.
Electronics Information covers: Ohm's law and electrical calculations, series and parallel circuits, electrical components (resistors, capacitors, diodes, transistors), basic electronics concepts (voltage, current, resistance, power), and electrical measurement tools. Questions are practical and focus on understanding how circuits work.
No. EI tests basic electrical knowledge that can be learned through study. Focus on understanding Ohm's law (V=IR), how series and parallel circuits differ, what common components do, and basic electrical safety. Many test takers learn this material specifically for the ASVAB.
EI is scored as a raw score converted to a standard score. EI contributes to several important line scores including Electronics (EL), General Technical (GT), and Skilled Technical (ST) scores. These line scores determine qualification for technical jobs like electronics technician, avionics, and communications.
