The number of electrons in 1 C of charges is

Options

  1. A6.25 10¹⁸
  2. B6.25 10¹⁶
  3. C6.25 10¹⁰
  4. D6.25 10¹²

Correct answer

A. 6.25 10¹⁸

Step-by-step solution

Charge, q=1 C If n be the total number of electrons in 1 C of charge, then q=n e aligned n &= q e &= 1 1.6 10⁻¹⁹ &=6.25 10¹⁸ electrons aligned
