What is the schematic symbol for a resistor?

• A. -II-, -I(-
• B. —||—
• C. —nnnnn---
• D. —\/\/\/\--

Answer: (D)

In schematics the resistor is shown as a jagged, zigzag line. That stepped, angular pattern is the standard symbol for resistance in many circuit drawings, especially in the US ANSI style (though some regions use a rectangular box instead). The zigzag visually communicates that the element resists current flow. The other options illustrate different components: the symbol with two parallel lines is a capacitor, which stores charge; the smooth wavy line shown isn’t the typical resistor symbol, and a plain straight line usually just represents a conductor with no resistance. So the jagged, zigzag line is the correct resistor symbol.
