MOTM

A friend who is tinkering with my modular asked me a question, I thought I'd
ask here. 

 

Let's say an MOTM module is rated at 25ma current draw. Is that a "maximum"
or an average.? He's wondering if the modules pull any significant current
if they are not patched into the audio chain. I had never thought of it that
way before... does it matter?

 

Thanks in advance!
