Electricity
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 .
