Question

ch 18 5. Doubly‑charged calcium ions, Ca2+, are released into your bloodstream and flow through your capillaries. The diameter of a capillary is about 8.00 μm, calcium ion concentrations are approximately 1.10 mol/m3, and typical electric current flow due to the Ca2+ ions is around 1.2 nA. Calculate the drift speed ?drift of the calcium ions.

?drift =

Answer 1

The problem is solved using the formula of current in a conductor.
