The capacitance of a capacitor is not affected by

distance between plates
area of plates
thickness of plates
all of the above

The correct answer is: A. distance between plates

The capacitance of a capacitor is a measure of its ability to store electric charge. It is proportional to the area of the plates and inversely proportional to the distance between them. The thickness of the plates does not affect the capacitance.

Here is a more detailed explanation of each option:

  • A. distance between plates: The capacitance of a capacitor is inversely proportional to the distance between the plates. This means that the closer the plates are together, the greater the capacitance.
  • B. area of plates: The capacitance of a capacitor is proportional to the area of the plates. This means that the larger the plates are, the greater the capacitance.
  • C. thickness of plates: The thickness of the plates does not affect the capacitance. This is because the electric field between the plates is only affected by the charge on the plates and the distance between them. The thickness of the plates does not affect either of these factors.

I hope this explanation was helpful!
