Please wait for the animation to completely load.

The animations show four charged conductors (position is given in meters and electric potential is given in volts). Restart.

1. Configuration 1: Rank the magnitude of the electric fields in the three regions between the conductors from largest to smallest. You can move the black circle around to show the voltage at any point.
2. Configuration 2: Rank the magnitude of the electric fields in the three regions between these conductors from largest to smallest.
3. Configuration 3: Rank the voltages on the four plates from largest to smallest. As you move the positive test charge around, the vector shows the strength of the force on the test charge.
