A total of `6.0xx10^(16)` electrons pass through any cross - section of a conducting wire per second. Find the current.

Text Solution

Verified by Experts

The total charge crossing the cross section in onesecond is,
`DeltaW=n e=6.0xx10^(16)xx1.6xx10^(-19)C=9.6xx10^(-3)C`
The value of current
`I=(DeltaQ)/(Deltat)=(9.6xx10^(-3)C)/(1s)=9.6xx10^(-3)A`
