1. Electric Potential
1.1. Is the work done per unit positive charge when a positive test charge is moved from infinity to that position, also called voltage (measured in volts or joules per coulomb).
1.2. Formula: electric potential energy/charge or V=Ep/Q
2. Equipotential Lines
2.1. Link points of equal voltage in an electric field, the lines cross the equipotential lines at right angles.
3. Potential Gradients
3.1. The rate of change of electric potential per unit charge of distance in a certain direction in an electric field.
4. Inverse Square Laws
4.1. When two electrons repel each other while being near
5. Coulomb's Law
5.1. In 1783, the French physicist Charles Augustin de Coulomb measured the electrostatic force between two electric charges.
5.1.1. He realized that the magnitud of the force between charges Q1 and Q2 was proportional to the product of Q1 and Q2, but inversely proportional to the square of the distance (r) between both.
5.2. The formula is: F=(kQ1Q2)/r^2
6. Electric Fields
6.1. All objects are surrounded by something called the "electric field".
6.1.1. An electric field is where a charged particle will experience a force.
6.1.1.1. They can be represented by "electric field lines".
6.1.1.1.1. The direction of the lines represent the direction of the field, shows the direction a positive charge will move.
6.1.1.1.2. The distance between the lines represent the strength of the field (the closer the lines, the stronger the field).
6.2. There exist two types of electric fields: the radial and the uniform.
6.2.1. Uniform: electric field parallel between two parallel plates, the a charge will experience the same force if it is in between the plates.
6.2.1.1. Formula: voltage/distance or E=V/d
6.2.1.1.1. E=volts per metre
6.2.2. Radial: the electric field around a charge extends radially out form the center
