Abstract:
In this lab we mapped the equi electromotive force lines of 3 different electrode setups: A dipole, two correspond bars, and lastly a hollow piston chamber between the two bars. Using the voltaic automobile potential we put up at different points on the setups, we calculated the value for the galvanising vault of heaven. For the first setup, the dipole, we found the electric field to be. For the second setup, the parallel bars, the electric field 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 rotund chi square value, meaning our data did not rifle well. Therefore I cannot accept the result that I achieved.
supposition:
The electrostatic force exerted by two armorial bearingsand over a distance can be represented by the equating:
(Eq. 1)
The constant, 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 charge exerted on a positive footrace charge at a point. To find the force that the electric field exerts on the test charge can be found alone 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 negative, the electric field would point inward 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 respect to a point at distance infinity. Thus the electric potential for a point P is then...If you want to get a full essay, order it on our website: Ordercustompaper.com
