Resistively heated filaments are used to deposit diamond or to act as a substrate in the manufacture of ceramic fibers. This article analyzes the effects of an AC power source, in particular the oscillation in filament temperature and its influence on the kinetic rates, as well as the vibration of the filament, when it is mounted in a state of tensile stress. These effects diminish when the filament gauge is large enough and the analysis can help to decide whether an AC or a DC power source should be used.
