Electric Fields

Electric Fields

1. Electric Field strength (E)

   • The force per unit positive charge
     • E = F/Q
       • E is a vector, it always has a direction
   • If a charged particle is put in a electric field it will experience a force.
     • E = Q/4πε₀r²
       • • Area under curve = Electric Potential
         • 1/r² relationship

2. Coulomb's Law

   • The force between two charges is directly proportional to the product of the charges and inversely proportional to the distance squared
     • F = qQ/4πε₀r²

3. A region of space where charged particles experience a force. it goes from positive to negative

4. Field lines

   • • Positive and negative point of charge
   • • Parallel Plate of charge
   • • Opposite point of charges
   • • Same point of charge
