Inclines to make right current (5)
I believe the answer is:
ramps
'inclines' is the definition.
(I know this)
'right current' is the wordplay.
'right' becomes 'r' (common abbreviation).
'current' becomes 'amps' (I've seen this before).
'r'+'amps'='RAMPS'
'to make' acts as a link.
(Other definitions for ramps that I've seen before include "Sloping passages" , "Gradients" , "Slopings passages" , "Small road ridges for prams" , "Slopes to calm traffic" .)
