Electric Charge | A fundamental property that leads to the electromagnetic interactions among particles that make up matter. |
Static Charge | Electric charges at rest; generally produced by friction or induction. |
Electrical Conductor | A material in which charges can move freely. |
Electrical Insulator | A material in which charges cannot move freely. |
Semiconductor | An element or compound that conducts electric current better than an insulator does but not as well as a conductor does. |
Electrical Current | The rate at which electric charges pass a given point. |
Resistance | In physical science, the opposition presented to the current by a material or device. |
Voltage | The amount of work to move a unit electric charge between two points; expressed in volts. |
Electrical Circuit | A set of electrical components connected such that they provide one or more complete paths for the movement of charges. |
Series Circuit | A circuit in which the parts are joined one after another such that the current in each part is the same. |
Parallel Circuit | A circuit in which parts are joined in branches such that the voltage across each part is the same. |
