Basic SI unit of electrical current (6)

I believe the answer is:

ampere

(Other definitions for ampere that I've seen before include "Unit of currency" , "Unit measured by 17 across" , "Current analyst" , "Unit of electrical current" , "Solenoid inventor" .)

I've seen this clue in The Sunday Times and The Times.
