MCQ
What is the maximum energy that can be stored in a capacitor?
  • A
    Depends on the maximum area of the capacitor.
  • B
    Depends on the maximum resistance offered.
  • ✓
    Depends on the maximum electric field.
  • D
    Depends on the maximum current passing through the capacitor.
✓

Answer

Correct option: C.
Depends on the maximum electric field.

The maximum energy that can be desirably stored in a capacitor is depends on the maximum electric field that the dielectric can withstand without breaking down. Therefore, capacitors of the same type have about the same maximum energy density, i.e. joules of energy per cubic meter.
