More than half of States embracing NY Opera's current shower (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
ammeter
'current shower' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
I also know that 'current' relates to this answer.
'more than half of states embracing ny opera's' is the wordplay.
I cannot quite see how this works, but
'more' could be 'm' and 'm' is found within the answer.
'opera' could be 'met' (Metropolitan Opera in New York) and 'met' is found in the answer.
The remaining letters 'aer' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ammeter that I've seen before include "Instrument to measure electric current" , "Current-measurer" , "Device that measures the flow of electrical current" , "Current-measuring instrument" , "Instrument measuring electrical current" .)
