Physics · Electrostatic Potential

हिन्दी

Consider the following statements regarding a parallel plate capacitor: (A) The capacitance \( C \) increases when the area of the plates is increased. (B) The capacitance \( C \) depends on the potential difference \( V \) applied across the plates. (C) The electric field between the plates is uniform away from the edges when \( d^2 \ll A \). (D) The SI unit of capacitance is equivalent to \( \text{C}\cdot\text{V}^{-1} \). How many of the above statements are correct?

  1. A
    Only one
  2. B
    Only two
  3. C
    Only three
  4. D
    All four

Correct answer · Option C

Only three

Explanation

Statements (A), (C), and (D) are correct. Statement (B) is incorrect because \( C \) is independent of \( V \). Hence, exactly three statements are correct.
