Electric Field and Electric Potential Prelab Assignment



Name:_______________________________ 4-digit Code Number:_______________________________

  1. Write Coulomb's Law in equation form and explain what the equation means. Do not simply translate the symbols from math into English, but rather explain the content of the law.
  2. What is an electric field line?
  3. What are equipotential surfaces? Are they necessarily physical surfaces?
  4. Why must electric field lines be perpendicular to equipotential surfaces?
  5. For this experiment, the exact voltage supplied to the circuit is not important. Why does it not matter?
