The size of the high power capacitors are larger.

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

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

Radhika said: (Mar 5, 2015)  
R is directly proportional to the area of the surface.

Bhagya said: (Jul 31, 2016)  
R = L/A so, R is inversely proportional to the area.

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

Resistivity is directly proportional to surface area.

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