When a wire carries a current of 1.20 A,...

When a wire carries a current of `1.20 A`, the drift velocity is `1.20xx10^-4 m//s`. What is the drift velocity when the current is `6.00 A`?

`i="ne"Av_d`ltbr. `i.e. v_d propi`
when current has increased from `9=1.2A` to `i=6.0A`, i.e five times, then drift velocity will increase to five times.
