Hi
Is there any relation between noise and power consumption?
If yes,what is it?How the noise affects power consumption?

 

The amount of noise I make rises as the square of my family's power consumption.

 

Noise this the amount of noise I make when the family's power consumption goes up.

Is it an answer to my question!!!!!!!

 

Noise from what?!!!!!!!

A single transistor can have a voltage gain as high as about 180 and it amplifies its own noise. Its noise is very low so its output level of the noise is very low and will not increase its power consumption.

A power amplifier can amplify mains hum noise and produce a high output power to a speaker. Then its power consumption is high.

 

Low noise circuits like preamps typically use larger quiescent current, because noise roughly rises as the impedance rises.
But the main question is noise WHERE? and power consumption of WHAT circuit?
For example electrical noise on primary produced by a switching converter could rise with load power.
