Blows a fuse as resistance fades (5)
I believe the answer is:
rages
'blows a fuse' is the definition.
(I've seen this in another clue)
'resistance fades' is the wordplay.
'resistance' becomes 'r' (electronics abbreviation).
'fades' becomes 'ages' (I can't explain this - if you can you should give a lot more credence to this answer).
'r'+'ages'='RAGES'
'as' is the link.
Can you help me to learn more?
(Other definitions for rages that I've seen before include "becomes furious" , "Fits of temper" , "speaks as Hitler!" , "gives anger vent" , "Storms" .)
