A copper wire has `3xx 10^(22)` free electrons in 0.021 m length. The drift velocity of electrons is found to be `2xx10^(-5)ms^(-1)`.
How many electrons would pass through a given cross-section of the wire in one second?

Text Solution

Given:
Number of electrons crossing lhe conductor
`(N.)/t=I/e=(4.5728)/(1.6xx10^(-19))=2,858xx10^(19)` electron/s
