A method provides modeling of surface roughness effect of an electrical conductor. The method includes identifying first protrusions of a first level using an original flat surface of the conductor as a first base surface and determining a first correction factor of the first level using parameters of the first protrusions. The method further includes identifying second protrusions of a second level using the first protrusions and the first base surface as a second base surface, and determining a second correction factor of the second level using parameters of the second protrusions and regarding the second base surface as being a smooth surface, the smooth surface being a surface of the conductor without surface roughness effect. A final correction factor of the conductor is determined by combining the first correction factor and the second correction factor.
