V_{tpd}\) can also be calculated as \(I R\) where \(R\) is the load resistance. Voltage is a measure of energy, and energy is always conserved. So the EMF \(E\) of a cell is equal to the sum of ...

IN a recent paper, 1 Gerlach and Schneiderhan have described some experiments on the electrical resistance of nickel as a function of the temperature and as a function of a longitudinal external ...

In this video, Jonny Nelson explains resistance. The current through a component depends on both the resistance of the component and the potential difference across the component.
