Electrical Calculations Exam Practice Japanese Vocabulary

This is your capstone lesson. Use it to turn knowledge into reliable exam execution.
Japanese Key Term
総復習（そうふくしゅう / comprehensive review）
Hiragana
そうふくしゅう
English Meaning
Comprehensive review
Simple Explanation
Final-week preparation should prioritize weak areas and decision speed, not random re-reading.
Detailed Explanation
Use a rotating review cycle. Day 1: calculations and unit conversion. Day 2: vocabulary and prompt words. Day 3: diagrams and wiring logic. Day 4: safety and protection behavior. Day 5: mixed mock set under timed conditions. Day 6: error log only. Day 7: light review and rest. Keep an error notebook with your top recurring mistakes and one corrective rule for each. This is the fastest path to stable performance.
Key Vocabulary
- 総復習（そうふくしゅう / comprehensive review）
- 時間配分（じかんはいぶん / time allocation）
- 見直し（みなおし / review check）
- 弱点（じゃくてん / weak point）
Formula
Final-week rule: timed practice + targeted correction + spaced review of weak points.
Worked Example
If you miss two leakage questions and one unit-conversion question, next session starts with those exact patterns before new material.
Exam Tips
Do not change study style every day. Stable method and repetition outperform last-minute topic hopping.
Common Exam Trap
Spending all time on favorite topics while ignoring recurring weak areas.
Site Reality in Japan
Consistent process and checklists are also how electrical teams reduce rework and mistakes on site.
Practice Question
You have one week left and keep missing unit conversion. What should you do first?
Answer
Schedule daily short unit-conversion drills before mixed mocks
Explanation
Fix high-frequency errors first. A small daily drill improves both speed and confidence quickly.
1. Two 30 ohm resistors are in parallel. What is total resistance?
Equal parallel resistors halve the value.
2. A bad joint has 0.5 ohms resistance. If 10 A flows, power loss at the joint is:
P = I^2 R = 100 x 0.5 = 50 W.
3. What is the meaning of 力率?
力率 means power factor.
4. In a series AC circuit, if total voltage is 100 V and resistor voltage is 80 V, the power factor is closest to:
cos(phi) = Vr / V = 80 / 100.
5. Which notation means single-phase three-wire?
1phi3W is single-phase three-wire.
6. Which notation means three-phase three-wire?
3phi3W is standard three-phase three-wire notation.
