The incandescent electric light has as its light source the heat that results from the ohmic resistance of the filament to the electric current. 白炽电灯光是发热光源，由电流流过灯丝里的欧姆电阻产生。
A relation between an increase in the ohmic resistance and the ohmic restriction resistance of a conducting plate with a sharply changing width is shown. 摘要论述了窄式陡变宽度导板的欧姆电阻增量和欧姆集聚电阻间的关系。
