The constant of proportionality is the resistance of the conductor Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co.

Mathematically, the law states that V = IR, where V is the voltage difference, I is the current in amperes, and R is the resistance in ohms. For a given voltage, higher resistance entails lower current flow. The American Heritage® Science Dictionary Copyright © 2011. Published by Houghton Mifflin Harcourt Publishing Company.
