Answer:
The main problem with the first electric lightbulb, which was invented by Thomas Edison in the late 19th century, was its short lifespan. The early incandescent lightbulbs were not very efficient and had a limited lifespan of only a few hours. This was due to the fact that the filaments used in these bulbs were made of carbon, and they would quickly burn out when exposed to high temperatures caused by the electric current passing through them. This limited the practicality and usability of early electric lightbulbs, as they needed frequent replacement, and it was not economically viable for widespread use in lighting applications.
Edison and other inventors and scientists continued to experiment and improve upon the early electric lightbulb design, eventually leading to the development of more efficient and longer-lasting incandescent lightbulbs using different filament materials, such as tungsten, which became the standard for many years. Today, there are various types of lightbulbs available, including incandescent, fluorescent, LED, and other energy-efficient options, which have overcome many of the limitations of the early electric lightbulbs and are widely used for lighting purposes in modern times.
