A wire carries a current of 1ampere .How many electrons pass a point in the wire an each second?

Question

anonymous · Answer

1c of charges flow in one second.. 
and charge on each electron is 1.6 multiplied by 10 raised to -16 c

so now can you tell .. how many electrons?

anonymous · Answer

-19 i mean sorry!

simple,

I=q/t

q=no of electrons*charge on an electron.
q=no of electrons*(1.6*10^-19)

use above equation,
$$I=(n*1.6*10^{-19})/t$$

separate "n"

$$n=(I*t)/(1.6*10^{-19})$$

substitute values,
$$n=(1*1)/(1.6*10^{-19})$$
n=$$6.25*10^{18} electrons$$
