POTENTIAL+AND+ELECTRIC+FIELD+STRENGTH+PRACTICAL

IB PHYSICS > IB IA EXPERIMENTS [|IA criteria checklist.doc] - always a good idea to look at this before submitting you work. =PRACTICAL: POTENTIAL AND ELECTRIC FIELD STRENGTH=

APPARATUS: PHET Charges and fields simulationopens in a new window.
The simulation is also on StudyWiz for quicker download.

PROCEDURE:

 * 1) Download and save the simulation. Place two charges a short distance apart, observe the electric field and then plot equipotential lines at appropriate intervals.
 * 2) Save the image with a screenshot.
 * 3) Draw a straight line through the two charges and plot a graph of potential against separation.
 * 4) Repeat for different configurations (positive/ negative; large/ small).

REPORT:
Include in a document your screenshots and graphs. Use them to confirm: Electric field strength = -potential gradient
