Intro to Current: In basic circuit terminology, any device that uses electric current to perform work (such as converting electrical energy to light, heat, or motion) is called a:

• A. Conductor
• B. Load
• C. Switch
• D. Battery

Answer: (B)

Verified step by step guidance

1. Understand the terminology used in basic electric circuits. A 'conductor' is a material that allows electric current to flow through it easily, such as copper wire.
2. Recognize that a 'switch' is a device used to open or close a circuit, controlling the flow of current but not performing work itself.
3. Know that a 'battery' is a source of electrical energy that provides the voltage needed to drive current through the circuit.
4. Identify that a 'load' is any device in the circuit that consumes electrical energy to perform work, such as producing light, heat, or motion.
5. Therefore, the correct term for a device that uses electric current to perform work is a 'load'.
