Which of the following is the correct way to describe the relationship between trace width and impedance in a PCB?
easy📝 Formula Fix Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall how trace width affects impedance
Wider traces have lower impedance because they allow easier current flow.Step 2: Confirm the inverse relationship
As trace width increases, impedance decreases.Final Answer:
Increasing trace width decreases impedance -> Option BQuick Check:
Trace width ↑ -> Impedance ↓ [OK]
Quick Trick: Wider trace means lower impedance [OK]
Common Mistakes:
MISTAKES- Thinking wider trace increases impedance
- Ignoring trace width effect on impedance
- Assuming length alone controls impedance
