To the tech savvy people of the 21st century, computers are but an indispensable part of life. With
information to search, data to store, people to communicate with, it is indeed hard to imagine
life without computers.
But just like any other electric gadget, a computer also runs on electric
energy and hence can be rendered useless during times of power shortage. So what happens if
while working on the computer, there is a sudden power cut? Will all the data that you have been
working on be lost and the work interrupted, just cause of inefficient electric supply? Well, that
would have been the case if Uninterruptable powers supply, better known as the UPS had not come
to our rescue. UPS is an apparatus designed to provide power to an electrical gadget, when the input
power supply falls. Differing from a generator in its ability to provide instant power to the load, UPS
is used to protect telecommunication apparatus, data sources, computers and other gadgets which
can be fatally affected due to sudden stoppage in power supply. In the presence of an input voltage,
the UPS functions as an ordinary power supply device, but on failure of current, the battery present
inside the UPS takes over and power is provided to the load, till the battery is exhausted.
