ELECTRICAL resistance...

Explanation:

You should be more specific in further questions you ask because "resistance" can be thermal, electrical, geological, -friction- and so on.

I suppose you mean electrical r.

Electrical resistance is found with this formula derived from Ohm's Law:

#R=V/I#

where...

#V# is electric potential difference (voltage)
#I# is the e. current
#R# is resistance
