Question

derive an expression for electric current in terms of drift velocity​

Answer 1

Answer:

I=nqAvd I = nqAv d.

Explanation:

The SI unit for current is the ampere (A), where 1 A = 1 C/s. Current is the flow of free charges, such as electrons and ions. Drift velocity vd is the average speed at which these charges move. Current I is proportional to drift velocity vd, as expressed in the relationship I=nqAvd I = nqAv d.
