What is the function of a conductor?

• A. Stores charge
• B. Increases resistance
• C. Transmits electricity or heat
• D. Converts mechanical energy

Answer: (C)

A conductor’s job is to provide a path for energy to move. In electrical systems, it allows electrons to flow with relatively little resistance, so electric current can travel from a source to components that use it. It also conducts heat well, so thermal energy can move through the material from hotter to cooler areas. This combination—carrying electricity and transferring heat—defines what a conductor does. The other options describe roles for different devices: storing charge is typical of a capacitor or battery, increasing resistance is what a resistor does (or what a material might do as it warms), and converting mechanical energy is the job of machines like motors or dynamos, not a conductor.
