What is the electrical load in a circuit?

• A. The device that consumes electrical power in a circuit
• B. The source of energy
• C. The wiring insulation
• D. The protective device

Answer: (A)

In an electrical circuit, the load is the part that actually uses the energy—anything that consumes power to do work, such as a lamp, a heater, or a motor. It converts electrical energy into light, heat, or motion. The energy source provides the voltage and current, but it isn’t the load itself. The wiring and insulation simply carry and protect the current, not consume energy. A protective device like a fuse or breaker is there to stop current for safety, not to use energy. So the best answer is the device that consumes electrical power in a circuit.
