To investigate experimentally how the resistance of a metallic conductor at constant temperature depends on length and obtain sufficient values to plot a graph of resistance (y-axis) and length ...

When plane electric waves of very high frequency are guided by any system of cylindrical conductors, the axes of the cylinders being normal to the plane of the waves ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...
