RAD 156 Elc, Mag, EM
RAD 156 Electricity, Magnetism, and EM
| Question | Answer |
|---|---|
| kinetic, thermal, electric, nuclear and electromagnetic are all forms of what: | Energy |
| The process of electric charges being added to or subtracted from an object is : | Electrification |
| Three methods of electrification are: | Friction, Contact, Induction |
| one object rubs against another and electrons travel from one to the other | Friction |
| two objects touch, permitting electrons to move from one to another | Contact |
| process of electrical fields acting on one another w/o contact | Induction |
| The study of fixed electric charges or electrons at rest | Electrostatics |
| 5 Laws of Electrostatics are : | Repulsion & attraction, Coulomb's Law, Distribution, Concentration, & Movement |
| Like charges repel; unlike charges attract | Repulsion & attraction |
| Force between 2 charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them | Coulomb's Law |
| __________ is the inverse square relationship between two 2 charges | Coulomb's Law |
| charges reside on the external surface of conductors and spread equally throughout | Distribution |
| Greatest distribution of charges will be along the surface and on the sharpest curve and/or roughest surface | Concentration |
| Only NEGATIVE charges move along solid conductors; Electrons move from HIGHEST concentration to LOWEST concentration | Movement |
| Object w/ more electrons | Negative charge |
| weak negative charge or an object with fewer electrons than another object | Positive charge |
| (+) to(-) poles | Conventional Electric Current |
| (-) to(+ ) poles (x-ray tube) | Actual Electron Flow |
| Study of electric charges in motion (describes electricity as we know it) | Electrodynamics |
| any substance through which electrons flow easily | Conductors |
| Aluminum, Gold, Copper, Water are: | Conductors |
| materials that resist electron flow | Insulators |
| Plastic, Rubber, Glass are: | Insulators |
| materials with the ability to conduct electricity under certain conditions and insulate under other conditions | Semiconductors |
| Silicon and germanium are what kind of conductors | Semiconductors |
| 4 Basic Factors that describe electron flow | Direction, Force, Quantity, Opposition |
| Quantity of electrons flowing | CURRENT |
| Force of electron travel | POTENTIAL DIFFERENCE |
