lamp is connected at

\mathrm{60}{\mkern 1mu} \mathrm{V}\,\,\,\mathrm{DC}

supply. The number of electrons passing through the lamp in

\mathrm{1}\,\,\mathrm{min}

is (the charge of electron

e = 1.6\,\, \times \,\,{10^{ - 19}}\,\,\mathrm{C}

View answer and explanation

Correct option: B

{10^{21}}

Option B (

{10^{21}}

) is correct because it is calculated by dividing the total charge passing through the lamp by the charge of a single electron.
