How many electrons constitute a current of one microampere per second\

Question

Professor PC Thomas Classes · Answer

$\mathrm{ne}=\mathrm{q} \quad \mathrm{q}=$ It $\quad \mathrm{ne}=$ It\ where $\mathrm{n}=$ no. of electrons.\ $\mathrm{e}=$ electronic charge in coulomb\ I = current in ampere\ $\mathrm{t}=$ time in seconds.\ $\mathrm{n}=\frac{\mathrm{It}}{\mathrm{e}}$\ $\mathrm{I}=1 \mu \mathrm{~A}$\ $=1 	imes 10^{-6} \mathrm{~A}$\ $\mathrm{e}=1.6 	imes 10^{-19} \mathrm{C}$\ $\mathrm{t}=1 \mathrm{~s}$
