Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.

Integrated Concepts Derive an expression for the current in a system like that in Figure 23.11, under the following conditions. The resistance between the rails is R, the rails and the moving red are identical in cross section A and have the same resistivity . The distance between the rails is l, and the rod moves at constant speed v perpendicular to the uniform field B. At time zero, the moving red is next to the resistance R.

Before World War II, some radios got power through a “resistance cord" that had a significant resistance. Such a resistance cord reduces the voltage to a desired level for the radio’s tubes and the like, and it saves the expense of a transformer.
