In a circuit, the load uses the energy provided by the source to do what?

• A. Uses energy to perform tasks like lighting or moving parts
• B. Returns energy to the source
• C. Stores energy without using it
• D. Blocks current flow

Answer: (A)

In a circuit, a load uses electrical energy to perform work by converting that energy into another form—like light from a lamp, motion from a motor, or heat from a heater. The energy supplied by the source is transformed by the load to do those tasks, which is the essential idea behind how circuits power real devices.

Energy being returned to the source isn’t how a typical load operates, and simply storing energy without using it isn’t the primary function of a load. Blocking current flow would prevent energy transfer altogether, so it doesn’t describe how the load uses energy to perform work.
