Passive Components Question

Not open for further replies.
interesting question
the primary common characteristic of passive components is "no power supply needed" .
that is, the component works without adding connections to some sort of power supply

quote from google-ing passive component:
"A passive component is an electronic component which can only receive energy,
which it can either dissipate, absorb or store it in an electric field or a magnetic field.
Passive elements do not need any form of electrical power to operate."

there are several types of passive components

based on the definition above, one could also add diodes and transformers,

other components, such as transistors and any integrated circuit, are active components,
because they need a power supply to operate correctly.
