In a circuit diagram, a zigzag pattern specifically represents a resistor. The zigzag line is a standardized symbol that helps identify resistors in schematic diagrams, making it easy for anyone reading the circuit to recognize where resistance is being applied within the circuit.

Resistors are components that oppose the flow of electric current, and they are characterized by their resistance value, which is measured in ohms. This is crucial for controlling the amount of current flowing through different parts of the circuit. Recognizing the zigzag pattern allows engineers and technicians to quickly assess how current might be managed and manipulated within the overall design of the system.

The other symbols in the choices provided represent different components. A battery is typically shown as one or more pairs of parallel lines, where one line is longer (representing the positive terminal). A capacitor is commonly depicted as two parallel lines with gaps between them, and an inductor is often illustrated as a series of loops or coils. Each of these components has a distinct symbol that differentiates it from a resistor, making it essential to understand these symbols for effective reading of circuit diagrams.
