PPT-Electricity: Coulomb’s Law and Circuits

Vocabulary Electric charge q exists due to excess or deficient electrons on an object Charge comes in two kinds positive and negative The unit of charge is the coulomb Electric current. Eng. .

Distinguish between being electrically neutral, negatively charged, and positively charged and identify excess charge.. Force is equal to minus gradient of potential energy. Definition of the operator “nabla”:. Nabla times a scalar function is gradient of the function, and it is a vector. 1. Example:. . Find force if potential energy is . A – S55E. B – N25W. C – 305. D – 355. 1. The strike of the plane represented by the great circle trace on the equal area plot at left is:. A – S55E. B – N25W. C – 305. D – 355. 305 or N55W. By: Raiden Foris.

The symbol . k. is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 10^9 N • m^2 / C^2. . Circuits. Activator. Essential Question:.

Electricity Electric Current Currents are the rate that electricity flows thru a wire 2 types of currents: Alternating Current (AC) electricity flows back-n-forth like in a house Direct Current (DC) electricity flows in one direction like in a battery Nature of science: . . Although Ohm and Barlow published their findings on the nature of electric current around the same time, little credence was given to Ohm. Barlow’s incorrect law was not initially criticized or investigated. This is a reflection of the nature of academia of the time with physics in Germany being largely non-mathematical and Barlow held in high respect in England. It indicates the need for the publication and peer review of research findings in recognized scientific journals.. :-. PRITESH DESAI. SWATI GAJERA. VISHAL GANGADIYA. VIVEK GARALA. BHAVESH GAUDANI.
