Between the charged plates of a capacitor there is:
- A a magnetic field
- B a cloud of electrons
- C an electric current
- D an 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.
