Question

One coulomb charge is equivalent to the charge contained in:

(a) 2.6 × 10¹⁹ electrons
(b) 6.2 × 10¹⁹ electrons
(c) 2.65 × 10¹⁸ electrons
(d) 6.25 × 10¹⁸ electrons

Solution

(d) 6.25 × 10¹⁸ electrons
Since the charge of an electron is $1.6 \times 10^{- 19} C$ , 6.25 × 10¹⁸ electrons taken together constitute (6.25 × 10¹⁸ × 1.6 × 10⁻¹⁹C) or 1 coulomb of charge.
