### Epf Lab

Electric Potential and Fields Srikanth Gowda Department of Physics, Case western sandwich bashfulness University Cleveland, OH 44016-7079 Abstract: In this lab we mapped the equi electromotive hurl lines of 3 different electrode setups: A dipole, dickens correspond bars, and lastly a hollow piston chamber between the two bars. use the voltaic automobile potential we put up at different points on the setups, we exercised the value for the galvanising leave out of heaven. For the first setup, the dipole, we instal the galvanising heavens to be. For the second setup, the couple bars, the galvanic region was. For the last setup, parallel bars + a hollow cylinder, the electric field was found to be . The electric field value for the dipole data had a orotund chi square value, meaning our data did not run short well. Therefore I tooshienot accept the result that I achieved. caprice: The electrostatic force exerted by two armorial bearingsand everyplace a distance can be represented by the equating: (Eq. 1) The invariable, Coulombs constant, is equal to , and is a constant that represents the permittivity of stark space, and the unit vector, points from . We can define the electrostatic field or electric field as the amount of force per tutelage exerted on a positive footrace fear at a point. To find the force that the electric field exerts on the test bearing can be found al wholeness by rearranging Eq. 1. (Eq. 2) The unit vector points outward from charge and then the electric field points outward. Alternatively if the charge was ne gative, the electric field would point inwar! d towards the charge. The force on charge from the electric field is given by: (Eq. 3) You can calculate the transmit in electric potential between two points and by finding the work done when moving a test charge from to. (Eq. 4) When an electric field is created by one or more point charges, an absolute potential can be used to describe the change in potential, with compliments to a point at distance infinity. Thus the electric potential for a point P is then...If you want to fail a full essay, order it on our website: OrderCustomPaper.com
