In electrical terminology, which term is defined as a material that allows heat and electricity to pass through it?

• A. Conductor
• B. Insulator
• C. Amp
• D. Volt

Answer: (A)

Conductor is the term for a material that allows both heat and electricity to pass through it. This happens because conductors have free charged particles, typically electrons, that move easily when a voltage is applied, creating an electric current. Those same mobile charges also transfer thermal energy, so heat flows through a conductor readily. Metals like copper and aluminum are classic examples, which is why wires are made from them. An insulator does the opposite; it resists both electrical current and heat transfer, making it useful for protection and insulation. Amp and volt are units, not materials, representing current and electrical potential difference respectively.
