Unit of resistance (3)

I believe the answer is:

ohm

'unit of resistance' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for ohm that I've seen before include "A little resistance" , "measure of resistance" , "SI unit of electrical resistance" , "Unit of electrical resistance (3)" , "lawmaker" .)

I've seen this clue in The Guardian, The Times, The Mirror, the King Feature Syndicate, The Sunday Times, the Sydney Morning Herald, the USA Today, The Wall Street Journal, the Universal, The New York Times, the Penny Press, the LA Times, The Sun and The Independent.
