Answer:
The light bulb is one of the wonders of the modern world. Found nearly everywhere on the planet, light bulbs are so common and widespread that it’s easy to forget how dependent we are on them. The light bulb is an electric light source that’s technically called a lamp. This term is, of course, also more commonly used by consumers to mean a portable type of lighting such as a table lamp or a desk lamp.
The most common type of “lamp” or bulb is the incandescent light bulb. These types of light bulbs are the oldest and simplest form of bulb technology, dating back to Thomas Edison’s experiments with filament types back in 1879.
