Assertion: led | /r/CapableOf | need by operation
Facets:
value: by using a simple series resistance
type: MANNER
value: with a current source
type: OTHER
Source sentences:
text: Therefore, LEDs normally cannot be operated with a constant voltage; the current needs to be stabilized, e.g. by operation with a current source, or by using a simple series resistance for connecting to a constant voltage supply.
