電験三種 理論ドリル − 計算問題を無限演習
This resource specializes in calculation problems for the "Theory" section of the Third-Class Electrical Engineer Examination. It features automatically generated problems with constantly changing values and a 3-step explanation, allowing for endless practice without rote memorization.
About 電験三種 理論ドリル − 計算問題を無限演習
This is a drill app specifically designed for the calculation problems that make up the "Theory" section, the first hurdle in the Third-Class Electrical Chief Engineer Examination.
■ Numbers Change Every Time, Preventing Rote Memorization
All problems are parametrically generated. Even within the same field, the numbers change each time a question is asked, so you won't end up "memorizing the answers and losing the practice." All generated problems are verified with the built-in calculation engine. You can solve virtually unlimited problems without worrying about answer errors.
■ Three-Step Explanation: Formula, Substitution, and Answer
All problems include explanation steps. The moment you make a mistake, you can instantly check "which formula to use, what to substitute, and how to arrive at the answer." The incorrect answer choices are based on common mistakes made by test-takers, such as "forgetting √3" or "changing m-1 to m," so you can also recognize your own stumbling blocks.
■ Covers 7 Areas of Theoretical Calculation
• DC Circuits (Equivalent Resistance, Voltage/Current Divider, Bridge Equilibrium)
• Electrostatics/Capacitors (Equivalent Capacitance, Electrostatic Energy, Coulomb's Law)
• Magnetism/Electromagnetic Force (F=Bil, Induced Electromotive Force, Magnetic Field of a Straight Current)
• Single-Phase AC (Impedance, Power Factor, RLC Series)
• Three-Phase AC (Y, Δ, Equivalent Transformation, Three-Phase Power)
• Electronics Theory (Operational Amplifier Amplification, Transistor)
• Electrical Measurement (Shrunkers, Multipliers, Error Rate)
■ Same Multiple Choice Format as the Actual Exam
A drill format with 10 questions per session, using four options: A, B, C, and D. The results screen allows you to review explanations for all questions. Ideal for repetition during commutes and breaks.
■ One-Time Purchase, No Ads, Offline Playable
You can practice the "DC Circuits" and "Electrostatics/Capacitors" areas for free. All 7 areas are unlocked with the Pro (one-time purchase) in-app purchase. There are no monthly fees or ads. All learning functions operate within the device and can be used even in areas without a signal.
[Please Note]
All questions in this app are original, automatically generated questions (no past questions are reproduced). This app is an unofficial app not affiliated with the examination body and does not guarantee passing the exam.
