Question

The number of electrons required to produce a total charge of 1.6 C is:

Options

• \[1.6 \times 10^{-19}\]

• \[10^{-19}\]

• \[10^{19}\]

• \[1.6 \times 10^{19}\]

Answer 1

Since the charge on one electron is \[1.6 \times 10^{-19} \text{ C}\], the number of electrons is \[n = \frac{1.6}{1.6 \times 10^{-19}} = 10^{19}\]. This shows how enormous the number of electrons flowing must be for even a small amount of charge.
