Question

establish relation between current and drift velocity ​

Answer 1

Answer:

Current I is proportional to drift velocity vd, as expressed in the relationship I=nqAvd I = nqAv d . Here, I is the current through a wire of cross-sectional area A. The wire's material has a free-charge density n, and each carrier has charge q and a drift velocity vd.

Answer 2

Current I is proportional to drift velocity vd, as expressed in the relationship I=nqAvd I = nqAv d . Here, I is the current through a wire of cross-sectional area A. The wire's material has a free-charge density n, and each carrier has charge q and a drift velocity vd.
