Electric charge
Unit 3, lesson 1-4
| Term | Definition |
|---|---|
| Electric charge | A fundemental property that leads to the electromagnet intrractions among particles that make up matter |
| Static electricity | Electric charge at rest; generally produced by fricyion 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 |
| Electric current | The rate at which electric charges pass a given point |
| Voltage | The amount of work to move a unit electric charge between two points; expressed in volts |
| Resistance | In physical science, the opposition presented to the current by the material or device |
| Electric circut | A set of electrical components connected such that they provide one or more complete paths for the movement of charges |
| Series circut | A circut in which the parts are joined one after another such that the current in each part is the same |
| Parallel circut | A circut in which the parts are joined in branches such thsy the voltage across each part is the same |
| Magnet | Any material that attracts iron or materials containing iron |
| Magnetic force | The force of attraction or repultion generated by moving or spinning electric charges |
| Magnetic pole | One of two points, such as the ends of a magnet, that have opposing magnetic qualities |
| Magnetic field | A region where a magnetic force can be detected |
| Electromagnetism | The interaction between electicity and magnetism |
| Electromagnet | A coil that has a soft iron core and that acts as a magnet when an electric current is in the coil |
