What symbol is used to denote electrical resistance?

Explanation:
Resistance is quantified in ohms, and the symbol for the ohm is the Greek letter omega, Ω. This symbol identifies the unit of resistance in circuits. In contrast, A denotes amperes (current), V denotes volts (voltage), and I is commonly used as the current variable in equations. So Ω is the correct symbol to denote electrical resistance.
