Given data
*The given current is I = 1 Ampere
*The given time is t = 1 s
The expression for the charge is given as
[tex]Q=I\times t[/tex]Substitute the known values in the above expression as
[tex]\begin{gathered} Q=1\times1 \\ =1\text{ C} \end{gathered}[/tex]Hence, 1 Coulomb of charge flows through each lamp
The formula for the number of electrons in one Coulomb of charge is calculated as
[tex]n=\frac{q}{e}[/tex]*Here e = 1.6 × 10^-19 C is the charge of the electron
Substitute the known values in the above expression as
[tex]\begin{gathered} n=\frac{1}{1.6\times10^{-19}} \\ =6.25\times10^{18}\text{ electrons} \end{gathered}[/tex]
