Item 7:

When a capacitor is being charged, the electric field inside is increasing from zero to its maximal value, which is determined by the applied voltage and the capacitance C.

Increasing field strength within a capacitor when being charged

On one side of the capacitor, electrons flow through the connecting wire to the inner surface and on the other side electrons flow from the surface to the connecting wire - leaving positive ions on the surface behind.

The following statements relate to the process of change of the electric field inside of the capacitor.

 

Please indicate which statement does correspond with what you know about this process.

 

  • 1) The electric field inside the capacitor is formed starting from the appearing negative electrons at one side to the appearing positive ions
    at the other side.
  • 2) The electric field inside the capacitor is formed starting from the appearing positive ions at one side to the negative electrons at the other side.
  • 3) The electric field inside the capacitor is formed starting symmetrically from both appearing charge carriers to the middle.
  • 4) The electric field inside of the capacitor is formed due to charges on the surface of the connecting wires.
