THE X-RAY CIRCUIT WITH QUESTIONS AND ANSWERS

THE X-RAY CIRCUIT WITH QUESTIONS AND ANSWERS What is Electrostatics? - Correct Answer->Is the study of charges at rest (not moving) What is Electrodynamics? - Correct Answer->Is the study of charges in motion In fluids, gases, and in a vacuum both positive and negative charges can move In solid materials only negative charges (electrons) can move What are the electrons moving during electrodynamics called? - Correct Answer->electricity Solid materials possess different abilities to conduct electricity and are classified as ______? - Correct Answer->Conductors Insulators Semiconductors Superconductors What are the characteristics of conductors? - Correct Answer->Electrons move freely Electrons can drift through a conductor at a rate of only 1 mm/sec, but an impulse or current travels at speed of light in vacuum (3x10^10 cm/sec) What are some examples of conductors? - Correct Answer->Metals & most liquids Gold Platinum Silver Copper The study of stationary electric charges is A. electromagnetism B. electrodynamics C. electronics D. electrostatics - Correct Answer->D. electrostatics What is the power source? - Correct Answer->Source of electrons (electricity) What are the symbols for power source? - Correct Answer->Alternating Current (wall outlet) or AC Direct Current (DC) a battery Capacitor (DC) What is a switch? - Correct Answer->Turns circuit on and off What is a resistor? - Correct Answer- CONTINUES...
