Topic hierarchy

18.1: Overview
Electric potential and field are related in that potential is a property of the field that describes the field’s action.
18.2: Equipotential Surfaces and Lines
An ideal conductor exists only in the world of theory; it has “ideal” properties that make calculations easy to perform.
18.3: Point Charge
The electric potential of a point charge Q is given by V = kQ/r.
18.4: Capacitors and Dielectrics
Capacitance is the measure of an object’s ability to store electric charge.
18.5: Applications
A cathode ray tube consists of a vacuum tube that contains one or more electron guns used to excite phosphors on a screen to produce images.
