ELECTRODYNAMICS the science of electric charges in motion
The Nature of an Electric Current an electric current consists of a flow of charged particles, which may occur under th following conditions, 1. in a vacuum, 2. in a glass, 3. in an ionic solution 4. in a metallic conductor
ELECTRIC CURRENT in a solid conductor, consists of a flow of electrons only
ELECTRIC CIRCUIT defined as the path over which the current flows
BATTERY converts chemical energy to electrical energy
GENERATOR converts mechanical energy to electrical energy
POTENTIAL DIFFERENCE difference in electrical potential energy between two points in an electric circuit
VOLT (the unit of potential difference) which will maintain a current of ampere in a circuit whose resistance is one ohm
ELECTROMOTIVE FORCE (emf) applies to the maximum difference of potential between the terminals of a battery
CURRENT defined as the amount of electric charge flowing per second
AMPERE the unit of current
RESISTANCE is that property of the circuit which opposes or hinders the flow of an electric current
OHM the unit of electrical resistance
The resistance of a conductor depends on Material, (conductors, semi-conductors, insulators) Length, Cross-Sectional Area, and Temperature
