About this app
Pass your electrician's exam without carrying a book.
VoltPrep is a practice-exam app for apprentices and journeymen sitting the residential, journeyman, or master electrician test. 1,000 questions, eleven topics, timed mock exams — all of it offline, with no account and no subscription.
WHY IT WORKS
Every question carries a worked explanation and a code article reference, so you learn why an answer is right instead of memorizing which letter it was. Answer choices reshuffle every session — you can't game position.
KNOW WHEN YOU'RE READY
The Exam Readiness score estimates what you'd score on exam day, weighted by how much each topic is actually worth on the paper. It names the two areas costing you the most, so your study time goes where it counts.
TIMED MOCK EXAMS
Residential, Journeyman, and Master presets built to real exam weighting and time limits. Get scored by topic and see exactly where the points went.
ELEVEN TOPICS
• Electrical theory and Ohm's law
• Calculations — voltage drop, conduit fill, box fill, ampacity
• Grounding and bonding
• Wiring methods and materials
• Overcurrent protection
• Motors and controls
• Transformers
• Services, feeders, and load calculations
• Safety and OSHA practice
• Code definitions
• Special occupancies and equipment
SPACED REPETITION
Flashcards bring questions back right before you'd forget them. Anything you miss lands in a review deck automatically.
FIELD CALCULATORS
Voltage drop, conduit fill, box fill, ampacity derating, motor FLC, transformer sizing — plus a formula sheet you'll keep using after the exam.
PRO — ONE-TIME PURCHASE
All 1,000 questions, no ads, unlimited mock exams, and full bank search. Buy once, keep it. No subscription, ever.
Free sample from every topic before you decide.
