Electrostatics Is the study of the interactions between electric charges that are not moving.
Electrostatics deals with things such as… charges conservation on electricity electric fields electrical potential and electrical potential difference
Charges with charges there are two types: positive = Lost electrons Negative = Gained electrons
Law of conservation of electric charges states that all of the electric charge in any process is zero there is also coulombs(C) (F=k(Q1Q2/r2) which shows change of charges.
Electric fields They exist in the space around the charged particle it is represented by lines that start on a positive charge and end on a negative charge. to test the force exerted on a charged particle in an electric field and uses the equation E=kQ/r2
Electrical potential is a point that equals the electric potential energy per unit charge placed at that point.(V=PE/Q) and the electrical potential due to a point charge (V=kQ/r) and as r approaches infinity V=0
Gauss’s law was created by Karl Friedrich Gauss Related to electric charge and electric field and is more general version of Coulomb’s law. involves the concept of electric flux which is an electric field passing through a given area. equation: Φ=EA(cos(θ))
Electrical potential differance the amount of work required to move a charge from point a to point b equation: V-V=-W/q fields and electrical potential are similar in that they both show the effects of any charge distribution but electric field is a vector and electrical potential is a scalar.
