Figure in charge, still (6)
I believe the answer is:
static
'still' is the definition.
(static can mean still or not moving)
'figure in charge' is the wordplay.
'figure' becomes 'stat' (statistic).
'in charge' becomes 'ic' (abbreviation for 'in charge').
'stat'+'ic'='STATIC'
(Other definitions for static that I've seen before include "Crakling or hissing noise caused by electrical interference" , "fixed" , "Still - crackling on the radio" , "it can shock and > ruin the reception" , "Not moving or changing" .)
