Question

Explain the flow of energy to the lamp from electrical energy.

A. Electrical energy from the plug is used to make electromagnetic energy in the form or light.
B. Electrical energy from the plug is converted into mechanical energy in the form or light and thermal energy in the form of heat.
C. Electrical energy from the plug is converted into electromagnetic energy in the form or light and thermal energy in the form of heat.
D. Electrical energy from the plug is converted into electromagnetic energy in the form or light and the remaining energy is lost as heat.

Answer 1

Electrical energy from an electrical outlet is transformed into both visible light and heat when used to power a lamp, resulting in electromagnetic energy in the form of light and thermal energy as heat.

Step-by-step explanation:

When considering the flow of energy to a lamp from electrical energy, the correct description is C. Electrical energy from the plug is converted into electromagnetic energy in the form of light and thermal energy in the form of heat. Electrical energy flows through the lamp's circuitry and as it encounters resistance within the filament of the lamp, it produces light (through incandescence in traditional bulbs or via excitation of gases in fluorescent lamps) and generates heat. The generation of light is a transformation into very pure form of radiant energy, which includes visible light, while the heat produced is due to the internal motion of atoms and molecules, representing the lamp's thermal energy content.
