Charges and fields

This simulation allows students to arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. They can plot equipotential lines, discover their relationship to the electric field and create models of dipoles, capacitors, and more!

Sample Learning Objectives include:

  • Determine the variables that affect the strength and direction of the electric field for a static arrangement of charges.
  • Investigate the variables that affect the strength of the electrostatic potential (voltage).
  • Explain equipotential lines and compare them to the electric field lines.
  • For an arrangement of static charges, predict the electric field lines. Verify the prediction using vector addition.
