DC circuitsQuestion 846 of 1506

A capacitor is connected to a DC source and charges. Where do the extra free electrons collect?

  1. On the plate connected to the positive side
  2. On the plate connected to the negative side of the source
  3. Equally on both plates
  4. In the dielectric only
Show answer

Correct answer: On the plate connected to the negative side of the source

Electrons are pushed onto the negative plate and drawn from the positive plate, so charge differs between the plates.
