What is a load?

What is a load?

• A. A device that generates electrical energy.
• B. The source of the circuit's voltage.
• C. A conductor with zero resistance.
• D. Anything that consumes electricity to create power, such as lights or motors.

Answer: (D)

In electrical circuits, the load is the device that uses electrical energy to perform work or produce another form of energy, such as light, heat, or motion. This is why a lamp or a motor fits the idea of a load—the circuit delivers power to these devices, and they convert that electrical energy into usable energy. So the correct choice describes devices that consume electricity to perform their function. A device that generates electrical energy is a source, not a load. A source provides the voltage or current, not consumes it. A conductor with zero resistance is an ideal wire that doesn’t consume power, so it isn’t a load either.
