Electric Field and Electric Potential Prelab Assignment

Name:_________________________ Lab Section:________ 4-digit Code Number:____________

  1. The "parallel plate" field plate used in this lab has two parallel conductors separated by (6.70 ± 0.05) cm. If the electric potential difference between the two parallel plates is (8.0 ± 0.5) v, what is the magnitude of the electric field between the plates with an error estimate. Recall that, E = ΔV /Δs.
  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?
