Electrical phenomena have been studied since antiquity, though advances in the science were not made until the seventeenth and eighteenth centuries. Practical applications for electricity however remained few, and it would not be until the late nineteenth century that [[Electrical engineering|engineers]] were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society. Electricity's extraordinary versatility as a means of providing energy means it can be put to an almost limitless set of applications which include [[motive power|transport]], [[HVAC|heating]], [[electric lighting|lighting]], [[Telecommunication|communications]], and [[computation]]. Electrical power is the backbone of modern industrial society, and is expected to remain so for the foreseeable future.<ref>
