Predict how wire width changes R and C
A routed wire keeps the same length but is made wider. Which first-order trend is generally correct?
Choose one
Answer choices
- A. Resistance increases and capacitance becomes zero.
- B. Resistance decreases, while total capacitance may increase because conductor geometry and coupling change.
- C. Resistance and capacitance are both independent of geometry.
- D. Resistance becomes negative.
