Why does resistance increase with cross sectional area?

The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through.

Why is resistance inversely proportional to length?

As the length is increased, the number of fixed positive ions increases and thus the collision of free electrons increases. This increases the resistance in a conductor. So, we can say that resistance is inversely proportional to surface area.

How does resistance vary with area of cross section?

Electrical resistance is directly proportional to the length (L) of the conductor and inversely proportional to the cross-sectional area (A). Resistance is inversely proportional to the area of cross-section. When the area of cross-section increases the resistance decreases and vice versa.

What is the relationship between resistance and area?

The relationship between resistance and the area of the cross section of a wire is inversely proportional . When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result.

How is resistance inversely proportional to?

But the resistance is inversely proportional to the cross sectional area of the conductor. If the conductor possesses a greater cross sectional area, then its resistance will be less.

Why does resistance decrease as area increases?

When cross sectional area increases the space of the elctrons to travel increases(simply explained). Therefore less amount of obstacles for the current. Therefore when area increases the resistance decreases.

How does resistance of a conductor vary with its length and area of cross section of the conductor?

The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. The resistance of a conductor, or circuit element, generally increases with increasing temperature.

How does electric resistance change with the change in the area of cross section of conductor?

Resistance of a conductor is inversally proportional to area of cross section that means if the area of cross section increases resistance decreases.

How does resistance vary with area of cross-section?

Why resistance decreases with increase in area?

Is resistance directly proportional to area of cross section?

When area of cross section of the conductor increases, the gap between electrons increases. So the probability of collision decreases. As a result the resistance decreases. So resistance is inversely proportional to area of cross section of the conductor.

Why does the resistance of a conductor decreases on increasing its cross-section area?

On increasing the area of cross-section, resistance decreases. This is because resistance is inversely proportional to area.
