Conductivity directly proportional to the surface area not resistivity.

How do you say resistivity is directly proportional to surface area?

Akshay said:   7 years ago
Resistivity is directly proportional to surface area.

Here A is the cross section area not the surface area. Don't confuse.

R = L/A so, R is inversely proportional to the area.

RADHIKA said:   9 years ago
R is directly proportional to the area of the surface.

In the case of resistor as power rating increases the size also increases inorder to facilitate higher area for power dissipation.

R = L/A then Resistance is Indirectly proportional to surface area.

The size of the high power capacitors are larger.
