* Resistance and Length: Resistance is directly proportional to the length of the conductor. This means that a longer conductor will have a higher resistance. Think of it like a longer and narrower pipe for water flow – the water encounters more resistance as it has to travel a longer distance.
* Resistance and Cross-Sectional Area: Resistance is inversely proportional to the cross-sectional area of the conductor. A larger cross-sectional area means less resistance, as the electrons have more space to flow.
* Constant Diagram: If the diagram stays the same, it implies that the cross-sectional area remains constant.
In summary: By increasing the length of the conductor while keeping the cross-sectional area constant, you are effectively increasing the resistance because the electrons have to travel a longer distance through the same amount of material.
