Walk in ready. Walk out licensed.
960 practice questions sorted by the sections of the official exams, an explanation for every answer, and a timed exam simulator for the 309A Construction and Maintenance Electrician or 442A Industrial Electrician exam that tells you when you're ready.
30 free questions, no credit card. Works on your phone, tablet or computer, and as an Android app on Google Play.
The 442A exam is organized into six sections. The 309A exam covers the same first five, with its own weighting, and has no process control section. Every SparkPrep question belongs to one of them, and the exam simulator draws questions in the same proportions as the official breakdown of the exam you choose, so your practice score reflects the exam you'll actually sit.
Short quizzes for each of the six sections, so you can work through the whole bank in order.
Each question comes with an explanation of why the right answer is right.
Flashcards and a hard-question list: flag what you miss and practice it until it sticks.
Phone, tablet or computer: your progress follows your account, tracked by section.
Choose the 309A or 442A: 100 questions, 4 hours, 70% to pass, the way the real exam is timed and weighted. Or a 50-question half exam in 2 hours.
Results by section after every exam, then targeted drills on the sections where you lost marks.
A process transmitter sends out 4 to 20 milliamps. What kind of signal is that?
D. Analog. A 4–20 mA transmitter outputs a continuously varying analog current proportional to the measured process variable.
What extinguishing agent should be used on an electrical wiring fire?
A. CO₂ (carbon dioxide). CO₂ (carbon dioxide) is the correct extinguishing agent for electrical fires (Class C). CO₂ is non-conductive, so it can be applied directly to energized electrical equipment without creating a shock hazard. Water and foam are electrically conductive and must never be applied to live electrical equipment.
