By JoJo's definition a resistor would be an active component because it actively converts electrical energy into thermal energy.

Semantics. Thermal energy is an unwanted byproduct.

In the electronics theatre, resistors, capacitors, diodes are considered passive components. What differentiates a diode from a transistor is one more dopiant region and a control lead. SCR's fall into active components too. And I'm not going to try to name all the active components in the electronics world.

 

In a resistor the conversion of electrical energy into thermal energy is of a deliberate intent.

 

hi Guys,
Please keep on TS's Topic.
would it be possible to amplify a signal with this resistor circuit?

Moderation

 

I ask my self (and all others who participate in this thread):
Is the process of "amplifying" an electric signal (voltage) not nothing else than converting DC into AC (resp. a corresponding AC spectrum)?
With other words: A real "amplification" without another energy source which is able to deliver some extra energy (for conversion) is not possible?

 

Can you amplify a signal with only resistors? No.
