Question 3
Calculate the number of electrons constituting one coulomb of charge.

Open in App

Solution

One electron possesses a charge of $1.6 \times 10^{- 19} C$
i.e., $1.6 \times 10^{- 19} C$ of charge is contained in 1 electron.
$∴$ 1 C of charge is contained in $\frac{1}{1.6 \times 10^{- 19}}$ electrons
$= 6.25 \times 10^{18} = 6 \times 10^{18}$
Therefore, $6 \times 10^{18}$ electrons constitute one coulomb of charge.
