1. Electric Field Lines

   • Positive
   • Negative
   • Positive -> Negative

2. Coulomb's Law

   • The force between 2 charges (Q1 and Q2) at a distance, r is:
   • This can be simplified by lumping the constants together into a single constant (k)

3. Electric Field Strength (E)

   • An electric field is a region where forces act on charges. It is measured in Newtons per Coulomb
   • Substituting the force from Coulomb's law you get the equation for Electric Field strength of a certain charge:
