Which symbol denotes a heater?

Which symbol denotes a heater?

• A. Inductor Symbol
• B. Diode Symbol
• C. Fuse Symbol
• D. Heater Symbol

Answer: (D)

In schematics, each component is identified by its own symbol, so you can quickly see what’s connected and how the circuit behaves. The symbol for a heater is a distinct heater symbol designed to represent a heating element, making it clear where heat is produced in the circuit. The coil-like symbol belongs to an inductor, which stores energy in a magnetic field. The triangle with a line is the diode, used for one-way current flow. The simple fuse symbol represents overcurrent protection. None of these depict heating elements, so the symbol that denotes a heater is the heater symbol.
