Which symbol is commonly used to denote electrical resistance in circuit diagrams?

Explanation:
In circuit diagrams, the quantity that describes how much a component resists current flow is represented by the symbol R, usually read as “R equals … ohms.” That makes R the label for resistance, and its value is given in ohms (Ω). By contrast, V denotes voltage, I denotes current, and C denotes capacitance. So when you see R labeled on a component or in a schematic, you know it’s the resistance you're dealing with. The other symbols correspond to the other electrical quantities, not resistance.
