Distant notice with some capacitance (5)
I believe the answer is:
farad
'some capacitance' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'distant notice' is the wordplay.
'distant' becomes 'far' (synonyms).
'notice' becomes 'ad' (both can mean an advertisement).
'far'+'ad'='FARAD'
'with' is the link.
Can you help me to learn more?
(Other definitions for farad that I've seen before include "SI unit of capacitance" , "Unit of electrical capacitance" , "this indicates how much to charge for storage" .)
