If a current of 0.5 ampere flows through a metallic wire for 2 hours then how many electrons would flow through the wire.

Explanation

Data: I=0.5 amp, `t=2 xx 60 xx 60 =7200 Q =It `
96500 Couloumbs `to 6.022 x 10^(23) e^(-)s" "=0.5 xx 2 xx 60 xx 60`
`3600 Coulombus to ? " "=3600 C`
`=(6.022 xx 10^(23) xx 3600)/(96500) =0.224 xx 10^(23) e^(-)s`.
