Proportionality Relationships for Electrical Conductors
- The relationship between resistance, length and cross-sectional area can be represented mathematically
-
- Resistance is directly proportional to length
-
- Resistance is inversely proportional to cross-sectional area (width, or thickness)
Proportional Relationships Between Resistance, Length & Cross-Sectional Area
Resistance is directly proportional to the length of the wire and indirectly proportional to the cross-sectional area
