1.	Charge on an electron is 1.6 × 10-19 C. How many electrons are required to accumulate a charge of one coulomb?
Answer» 1 electron = 1.6 × 10^-19 C ∴ 1 C = \(\frac{1}{1.6\times10^{-19}}\) electrons = 0.625 × 10¹⁹electrons ……. (Taking reciprocal from log table) = 6.25 × 10¹⁸electrons Hence, 6.25 × 10¹⁸ electrons are required to accumulate a charge of one coulomb.

Charge on an electron is 1.6 × 10-19 C. How many electrons are required to accumulate a charge of one coulomb?

Answer»

1 electron = 1.6 × 10^-19 C

∴ 1 C = \(\frac{1}{1.6\times10^{-19}}\) electrons

= 0.625 × 10¹⁹electrons

……. (Taking reciprocal from log table)

= 6.25 × 10¹⁸electrons

Hence, 6.25 × 10¹⁸ electrons are required to accumulate a charge of one coulomb.
