Question

When 1 coulomb charge flows through a conductor, the number of electrons which flow through the conductor are:

पर्याय

• 6.25 × 10¹⁹ electron

• 5.26 × 10¹⁹ electrons

• 6.25 × 10¹⁸ electrons

• 6.25 × 10¹⁶ electrons

Answer 1

6.25 × 10¹⁸ electrons

Explanation:

Charge on one electron is 1.6 × 10⁻¹⁹ C.

Number of electrons in 1 C is $$n = \frac{1}{1.6 \times 10^{-19}} = 6.25 \times 10^{18}$$.
