One is laid bare by [WizardTim], as he cross-sections a 20KV high-voltage diode. A conventional low-voltage silicon diode has a forward voltage drop of about 0.7V and a relatively low maximum ...

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 ...

The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist. The angle of twist for a section of length L ...
