In a light bulb, electrical energy is transformed into light energy and heat energy.
In a compact fluorescent light bulb, electrical energy is transformed into light energy through the excitation of mercury vapor atoms inside the bulb. Some electrical energy is also transformed into heat energy due to resistance in the bulb's circuitry and the phosphor coating on the bulb.
light and heat energy occur in a light bulb when it is turned on.
electrical energy ------> light & heat energy.
A lamp shade does not undergo energy transformations itself. It simply diffuses and directs the light emitted by the light bulb within. The energy transformation occurs within the light bulb, where electrical energy is converted to light energy and heat.
science quiz+the answer is chemical - electrical - light

No, a light bulb cannot blow out if it is turned off. Blown light bulbs occur when they are turned on due to the filament burning out or electrical issues.
In a light bulb, electrical energy is transformed into light and heat energy. When an electric current passes through the filament of the bulb, the resistance of the filament causes it to heat up and emit light. Some of the electrical energy is also converted into heat energy due to the inefficiencies in the conversion process.
The battery connected to the bulb has the potential chemical energy in it when it is connected by means of wire to the bulb the chemical energy in the battery is converted to the electrical energy which flows through the wire to the bulb glows the bulb which is a form of light energy after some time the bulb starts emitting heat which is heat energy.
The energy transformations that I would mention are as follows:Chemical Potential Energy --> Electrical Energy (In Battery)Electrical Energy --> Light Energy (In Bulb)Electrical Energy --> Heat Energy (In Bulb)Transformations 2 and 3 happen at the same time, because 3 is a side-effect of the intended transformation 2. I can't think of any other transformations, unless you wanted to consider the process of making the battery, or take the example of an unconventional flashlight.
Mechanical
Some examples of energy transformations in everyday applications include: When a light bulb converts electrical energy into light and heat energy. When a car engine converts chemical energy from gasoline into kinetic energy to move the vehicle. When a solar panel converts sunlight into electrical energy to power a home.
