An object is called as a good conductor of electricity when it allows the electrons to flow within it easily (for example a copper rod). Resistance it the opposition to the f â¦ low of electrons through it.
The Ambush of the steamboat J. R. Williams, which was carrying supplies from Fort Smith to Fort Gibson along the Arkansas River on July 16, 1863 demonstrated this. The steamboat was destroyed, the cargo was lost, and the tiny Union escort was run off. The loss did not affect the Union war effort, however.
Goods were carried via steamships (across the Atlantic) vs. horse-drawn wagons & by boats along rivers & canals. As steam powered ships were making their debut, the steam locomotive (train) was coming into use, to transport goods and people. Eventually, a process was developed for road construction.
