A wire-wound resistor is made by winding a piece of resistive wire around a ceramic core.

• A. False
• B. True
• C. Not sure
• D. Cannot be determined

Answer: (B)

Wire-wound resistor construction is being tested here. A resistive element, usually nichrome or another alloy, is wound around a ceramic core (former). The ceramic provides solid mechanical support and electrical insulation from the leads, while the winding creates the resistance from the chosen length and cross-section of the wire. This setup is standard for high-power resistors because it efficiently handles heat and keeps resistance stable under load. So, describing a resistor built by winding resistive wire around a ceramic core matches how these components are actually made, making the true choice the best one.
