Problem 26.2: Describe the charge distribution and find the electric potential across a capacitor

Please wait for the animation to completely load.

A parallel-plate capacitor is shown. A battery connects the two plates together but is not shown. Position and electric field strength are shown when you drag the mouse (position is given in meters and electric field strength is given in newtons/coulomb). Restart.

  1. Is the green plate positively charged, negatively charged, or neutral? Explain.
  2. Is the purple plate positively charged, negatively charged, or neutral? Explain.
  3. Sketch a diagram of the charge distribution on the plates.
  4. What is the voltage of the battery that connects the two plates?
