Estimate the magnitude of currect that passes through a wire , if 0.1 mol of electrons flow through it in 40 min. (Assume , Avagadro's number `=6.0 xx 10^(23)` )

Options

A. `4 A`
B. `9 A`
C. `12 A`
D. `14 A`

Answer

A

Explanation

Given number of electrons n = 0.1 mol and time of flow , t= 40 min = 2400 s
Current I `= (nQ)/t = (0.1 xx 6xx 10^(23) xx 1.6 xx 10 ^(-19)) /(2400)`
`rArr I =4A`
