Terms | Definitions |
|---|---|
 Electrostatics | Electricity at rest. They involve electric charges, the forces between them, and their behavior in materials |
| Electrical forces | Pair of forces acting on you at all times arise from particles in atoms |
| The fundamental rule at the base of all electrical phenomena | Like charges repel; opposite charges attract |
| Ion | Charged atom |
| Positive ion | A net positive charge, has lost one or more electrons |
| Negative ion | A net negative charge, has gained one or more electrons |
| Circuit | A complete path |
| Voltage | Electric pressure that can produce a flow of charge |
| Current | Flow of charge |
| Direct Current | When flow takes place along one direction |
| Alternating Current | When charge flows to and fro |
| Power | Rate at which energy is transfered |
| Potential Difference | Difference in potential voltage |
| Electric Current | Flow of electric charge |
| Conduction Electrons | Moving electrons |
| Amperes | Measure of electric current |
| Conducters | Materials in which electrons are tightly bound |
| Semiconducters | Materials that can behave as insulators or conducters |
| Insulators | Materials in which electrons are tightly bound |
| Superconducters | Materials that supply an infinite conductivity |
