If a current of one ampere flows through a metal wire for one hour, how many electrons would flow through the wire?

Text Solution

Verified by Experts

Current strength (i) = 1 amp, time (t) = 1 hr = 3600s
Quantity of electricity `(Q)=1xx3600=3600` coulomb
Number of electrons flown through the wire `=("Quantity of electricity")/(96500)xx6.023xx10^(23)`
`(3600xx6.023xx10^(23))/(96500)=2.24xx10^(22)`.
