"They run off eckeltricity, do they? Ah yes, I can see the plugs. I collect plugs. And batteries. Got a very large collection of batteries. My wife thinks I'm mad, but there you are."

Electricity is a form of energy used by Muggles to power most of their technology.

Electricity and magic

Magic was known to interfere with the functionality of Muggle technologies powered by electricity.[1] Most Muggle electronics – including computers, radar, and bugging devices – did not work in Hogwarts's magical environment.[1] However, exceptions to this rule could be made for devices that could run off of "the magical atmosphere," such as wizarding cameras.[2]

Muggle usage of electricity in their technology was part of the curriculum of the Muggle Studies class at Hogwarts School of Witchcraft and Wizardry. In 1993, Harry Potter and Ron Weasley spotted Hermione working on an essay titled "Explain Why Muggles Need Electricity" for this class.[3]

Chizpurfles would sometimes attack Muggle electrical items in the absence of magical items to consume, which sometimes explained the sudden failure of new electrical goods.[4]

Wizardkind in general apparently had little to no in-depth knowledge of electricity, as Arthur Weasley would go as far as to mispronounce the word itself, even when weather-based phenomenon such as lightning occurs in the wizarding world. Arthur was highly fascinated by electricity and kept a collection of batteries and plugs.[5] Professor Silvanus Kettleburn said in the 1987–1988 school year that he had once been electrocuted.[6]

The Weasleys' Wizard Wheezes had a product known as Electric Shock Shake.[7]

Wizards could produce a defensive charge to shock away attackers.[8] In fact, a variety of spells were capable of generating or mimicking the properties of electricity, such as Baubillious,[9] or the Tempest Jinx.[10]
