In electrical schematics, symbols are used to represent which property of a resistor?

• A. Voltage Rating
• B. Color Code
• C. Resistance
• D. Physical Size

Answer: (C)

Resistors in schematics are represented to convey their main electrical role: resistance. The symbol stands for a component whose defining property is how much it resists current, measured in ohms. In diagrams you’ll usually see a nearby value like 1kΩ, which tells you the exact resistance you’d use in the circuit. The symbol itself doesn’t specify voltage rating or physical size; those are separate specifications you’d find in the part’s datasheet or notes. Real resistors use color bands to indicate resistance and tolerance, but that color code applies to the physical part, not the schematic symbol.
