State electricity? (5)
I believe the answer is:
power
I believe this clue is a double definition.
'state' is the first definition.
(power is a kind of state)
'electricity?' is the second definition.
(electricity is a kind of power)
(Other definitions for power that I've seen before include "product" , "Ability (to do something)" , "Rate of doing work" , "Physical force, ability" , "See 12" .)
