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 ...

A second experiment can be carried out to investigate experimentally how the resistance of a metallic conductor at constant temperature depends on the area of cross section. The above experiment ...

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of elementary school physics canon. But the world is messier than a textbook. Scientists have sought to ...
