ASVAB – Electronics Information (EI) Test

The Electronics Information Subtest is designed to measure your understanding of electricity principles, currents, radio, television, engines, magnets and more.  If you have an interest in electronics and/or want to pursue a military job in electronics, this is the subtest for you!  On the CAT-ASVAB, you’ll need to answer 16 questions in 8 minutes and on the paper version of the test you’ll need to answer 20 questions in 9 minutes.

Here are some sample questions that may appear on the test:

  • What does Ohm’s Law state?
  • What is the highest frequency that a radar can operate at?
  • How do you measure electrical power?

This subtest is really designed for people who are interested in electronics, which means if that is not something you are interested in you don’t have to do well on this part of the ASVAB. The Electronics Information subtest is not included in your AFQT score.  On the other hand, if you want to pursue a military job that involves electronics, and there are many that do, you will want to do your best on this section.
