electric charge, electric field

and static charge

ELECTRIC CHARGE is a physical quantity of matter which causes it to

experience a force when near other electrically charged matter. Classically, electric charge comes in two types, called positive and negative.

Example picture:

ELECTRIC FIELD is a vector field with SI units of new tons per

coulomb (N C−1) or, equivalently, volts per metro (V m−1). The SI base units of the electric field are kg·m·s−3·A−1. The strength or magnitude of the field at a given point is defined as the force that would be exerted on a positive test charge of 1 coulomb placed at that point.

Example pictures:

STATIC CHARGE refers to the build up of electric charge on the

surface of objects. The static charges remain on an object until they either bleed off to ground or are quickly neutralized by a discharge. Static electricity can be contrasted with current electricity , which can be delivered through wires as a power source.
