PPT-Physics 05: Electric Currents

BY HEI MAN KWOK 12N03S 51 electric potential difference current and resistance Model of electric conduction in a metal energy transfer Charge carriers have kinetic energy These collide with lattice ions . Ensure the ultimate safety of your horses, cattle, sheep, livestock, dogs, and other pets with high tensile fence or other electric fencing. Our farm fencing accessories and electric horse fence supplies are also ideal for deterring predators, deer, and other garden pests. Wind-driven surface currents. Figure 7-4. Ocean Circulation Animation. Ocean Currents. Ocean currents- are stream-like movements of water. Ocean currents affect our weather and climate. 2 Types:. 1) Surface Currents. magnetism. Faraday’s Law of Electromagnetic Induction. induced currents. electric generator. eddy currents. Electromagnetic Waves (Maxwell & Hertz). 1. Basic facts of Magnetism. Oersted. . discovered that a compass needle responded to the a current in a loop of wire. http. ://oceanexplorer.noaa.gov/edu/learning/player/lesson08.. html. . . I. . Ocean . currents = Stream like movements of water. A. Surface currents. = occur near or at the surface of the ocean. Can reach 100 m deep or deeper. Is it possible to light a bulb . with a battery using only one wire?. Yes. No. I have no idea. NEXUS/Physics Clicker Questions. Which of the arrangements shown . will light the bulb?. Only A. Only B. Electric current. . is the rate of electron flow past a specific point in the circuit (how . fast . electrons pass . through a . point in the wire).. The symbol for electric current is . I. .. The units of electric current is . Key Points. Ohm’s Law. Resistivity. Electric Power. Alternating Current. References. . 18-1,2,3,4,5,6,7. Electric current is the rate of flow of charge through a conductor:. Unit of electric current: the ampere, . Created by Winds. Coriolis Effect- The shifting of ocean currents and surface winds from their expected paths caused by the rotation of the earth. Gulf Steam – ocean current in the northern Atlantic ocean, brings warm water from Africa to the Americas. Weather Patterns. Weather pattern’s are described as prolonged temperature changes over a specific area for example seasons.. Weather patterns can also be described as a period for which natural disasters are prevalent ex. Hurricane season, tornado season, blizzards. Earth/Space. S.W.B.A.T.. Explain how winds and the . Coriolis. effect influence surface currents. Discuss the temperatures of coastal waters. Describe density currents and how they affect Earth. Surface Currents. Highways in the Sea. What forces are responsible for currents?. Wind. : transfers energy through friction on surface; causes currents and waves. Sea level. : steeper slope=greater pressure gradient=drives a larger, faster current. How do different currents form. What is upwelling. What do ocean currents transfer. Predict. T F. Ocean currents are always cold. C. ontinents affect the direction of currents. Currents only flow near the surface of the ocean. Learn how to excel in AP Physics with this comprehensive guide.
