Between the charged plates of a capacitor there is:

  1. Aa magnetic field
  2. Ba cloud of electrons
  3. Can electric current
  4. Dan electrostatic field

Correct answer: D — an electrostatic field. From the official ISED question bank, verified word for word.

Why

When a capacitor holds a charge, opposite voltages on its plates create a steady force field in the gap between them. The full explanation — and one for every question — is in Pro.
