PHY2049L Individual Work Lab 3: Electric Field and Potential Valentina Espinosa Brief Description Coulomb's Law describes the force that one charged particle exerts on a second charged particle. In this experiment we are mapping the potential in the space around a pair of charged objects and finding out what can be extracted regarding the associated electric field. Preliminary Questions 1. What is meant by "voltage?" 2. If E is the gradient of potential, then 1 N/C should be the same as 1 V/m. Show that this is true. You may need to look up the definition of the volt. 3. What is the value of E inside a conductor, charged or uncharged? 4. What can you say about the potential inside a conductor, charged or uncharged?
