R denotes resistance. Resistance is the property that opposes the flow of electric current, and it is measured in ohms. In the relationship V = I R, the R part is what links current to voltage through the resistance. Because of this, the quantity described by the letter R is resistance, whose units are ohms. The other quantities have different symbols—voltage is V, current is I, and power is P—so they don’t match the letter R.
