Electrical field: property of space around a charged object that causes forces on other charged objects. Electric field lines: lines representing the direction of electric field. Electric field strength: ratio of force exerted by field on a tiny test charge to that change. Electric generator: device converting mechanical energy into electrical energy. Electric potential: ratio of electric potential energy to charge. Electric potential difference: difference in electric potential between two points. Electric potential energy: energy of a charged body in an electrical field. Electron gas model: description of current flow through conductors. Electroscope: device to detect electric charges.
Electrostatics: study of properties and results of electric charges at rest. Equivalent resistance: single resistance that could replace several resistors. Galvanometer: device used to measure very small currents.
Ohm: SI unit of resistance; one volt per ampere.
Ohm’s law: resistance of object is constant, independent of voltage across it. Piezoelectricity: electric potential produced by deforming...
