Usually credited to Thomas Edison and MIchael Faraday respectively.

The concept of electric fields was introduced by Michael Faraday. However 25 years before Faraday's birth Luigi Galvani began investigating the action of static electricity upon the muscles of frogs and when Faraday was 9 years old Alessandro Volta developed the voltaic pile, a forerunner of the electric battery. Faraday was a contemporary of other names synonymous with research into electricity such as Georg Simon Ohm and Andr�-Marie Amp�re.

Static electricity itself was known of by the ancient Greeks and Babylonians.

As for Edison, he neither invented nor was the first person to patent the incandescent lightbulb.

kempies answer shows why I put 'usually credited to'. If you are doing a quiz or something, its the answer they are looking for, but is sort of wrong. In the same way, James Watt did not invent the steam engine, but it is usually credited to him.

The discoverred electricity question is difficult to answer because the question is not really very precise.

The ancient Greeks new that amber could produce static electric effects and Otto von Guericke invented the first electro-static generator in 1650. 150 years later Allesandro Volta invented the ecectric battery.

Faraday's great contribution on the practical side was the invention of the first electric motor. A piece of wire going round in a bath of mercury. It didn't impress the prime minister Gladstone who asked what use it was - Faraday famously replied "Sir, one day you may tax it"
