Step-by-Step Solution
Solution:
Step 1: Understand coil alignment impact
Charging efficiency drops if coils are misaligned or too far apart.Step 2: Identify solution for off-center parking
Using larger or multiple coils increases coverage area, allowing good induction even if off-center.Step 3: Evaluate other options
Increasing power output may waste energy; reducing battery size is unrelated; perfect centering is impractical.Final Answer:
Use a larger coil or multiple coils to cover more area -> Option CQuick Check:
Larger/multiple coils = better coverage = efficient charging [OK]
Quick Trick: Larger or multiple coils fix off-center charging issues [OK]
Common Mistakes:
- Thinking increasing power output solves misalignment
- Believing battery size affects charging coil efficiency
- Assuming perfect centering is always possible
