I got the following brainteaser I can't handle with: what power we'll
get on a resistor powered from 100W amplifier set on the level -40dB,
when the source is a CD-player producing white noise at level -36 dB ?
What current flows thru that resistor ? We assume, that all the

To save me scouring hordes of websites while currently suffering a 33.6
connection, does anyone know off the top of their head of a simple 3-terminal
