Do all these movements of charged particles count as electric current?

[cathole]

Which of the following would be considered a current?

a negative ions flowing in a liquid
b electrons moving in a vacuum
c positive ions flowing in a liquid
d electrons moving in a wire
e ions moving in a vacuum

I presume all of these would be electric currents after reading this definition...

Electric current means, depending on the context, a flow of electric charge (a phenomenon) or the rate of flow of electric charge (a quantity).[1] This flowing electric charge is typically carried by moving electrons, in a conductor such as wire; in an electrolyte, it is instead carried by ions, and, in a plasma, by both.[2]

"flow of electric charge"

I believe a-e are all electric charges.

Please help me confirm this... Thank you in advance for any help you can give.

Current is simply movement of charged particles, usually caused by a potential difference (voltage). All of these are examples of current, despite the charge.

All of those answers are would be considered currents. Fact.
