- n. a property of certain of the fundamental particles of which matter is composed, called also electric charge, and being of two types, designated positive and negative; the property of electric charge on a particle or physical body creates a force field which affects other particles or bodies possessing electric charge; positive charges create a repulsive force between them, and negative charges also create a repulsive force. A positively charged body and a negatively charged body will create an attractive force between them. The unit of electrical charge is the coulomb, and the intensity of the force field at any point is measured in volts.
- n. any of several phenomena associated with the accumulation or movement of electrically charged particles within material bodies, classified as static electricity and electric current. Static electricity is often observed in everyday life, when it causes certain materials to cling together; when sufficient static charge is accumulated, an electric current may pass through the air between two charged bodies, and is observed as a visible spark; when the spark passes from a human body to another object it may be felt as a mild to strong painful sensation. Electricity in the form of electric current is put to many practical uses in electrical and electronic devices. Lightning is also known to be a form of electric current passing between clouds and the ground, or between two clouds. Electric currents may produce heat, light, concussion, and often chemical changes when passed between objects or through any imperfectly conducting substance or space. Accumulation of electrical charge or generation of a voltage differnce between two parts of a complex object may be caused by any of a variety of disturbances of molecular equilibrium, whether from a chemical, physical, or mechanical, cause. Electric current in metals and most other solid coductors is carried by the movement of electrons from one part of the metal to another. In ionic solutions and in semiconductors, other types of movement of charged particles may be responsible for the observed electrical current.
- n. The science which studies the phenomena and laws of electricity; electrical science.
- n. Fig.: excitement, anticipation, or emotional tension, usually caused by the occurrence or expectation of something unusual or important.
from The Century Dictionary and Cyclopedia
- n. In physics, a name denoting the cause of an important class of phenomena of attraction and repulsion, chemical decomposition, etc., or, collectively, these phenomena themselves.

"I applied for letters patent for my system of communicating intelligence at a distance by electricity, differing in all respects from Messrs. Wheatstone and Cooke's system, invented five years before theirs, and having nothing in common in the whole system but the use of _electricity_ on _metallic conductors_, for which use no one could obtain an exclusive privilege, since this much had been used for nearly one hundred years.
The term electricity is derived from the Greek word ηλεκτρον, amber.
Furthermore it does not need electricity, which is an important requirement given that disasters usually result in electricity supplies being disrupted, either temporarily or otherwise.
“It is a new century, and what we call electricity is its God,” wrote the romantic historian Henry Adams from Paris.
The biggest draw on our electricity is our ceiling fans, which have been going non-stop during April and May.
From the smoky station out of which the train passed the night before, along the slender wire stretched on rough poles at the side of the track, a spark of that mysterious something which we call electricity flashed at the moment he returned the watch to his pocket; and in five minutes 'time, the station-master came out on the platform,
From the first breath of flame, burning out the secret of the Dust to the last shadow of the dust -- the breathless, soundless shadow of the dust, which he calls electricity -- the man worships the invisible, the intangible.
It is like that subtle something which we call electricity; we can play with it, command it, lead it, neutralise it and die of it, make light and heat with it, or language and sound, kill with it and cure with it, while absolutely ignorant of its nature.
For example, here is this mysterious force that we call electricity, which is flashing such light in our homes and through our streets as the world has never known before.
And now, before this new manifestation of that form of cosmic vitality which we call electricity,
