What kind of energy transformation occurs when a light bulb is switched on?

When a light bulb is switched on, electrical energy is transformed into light energy. This process involves the flow of electric current through the filament or LED material within the bulb. As the electrical energy passes through, it excites the atoms or ions in the bulb's material, causing them to release energy in the form of light. This transformation is a fundamental concept in understanding how electric circuits work and the operation of various types of light bulbs, such as incandescent or LED bulbs. The light produced is directly a result of the conversion of electrical energy, which is why this answer is the most accurate representation of the energy transformation at play when a light bulb is activated.
