Assertion: diode's resistance | /r/HasAspect | other source of power
Facets:
Source sentences:
text: Therefore a negative static resistance must have some other source of power.
text: Work must be done on the charges by some source of energy in the device, to make them move toward the positive terminal against the electric field, so conservation of energy requires that negative static resistances have a source of power.
text: Therefore a negative static resistance must have some other source of power.
