When a Current I₁ = 1

Multiple Choice

When a current I₁ = 1.3 A passes through a wire of cross-sectional area A₁ = 5 mm² the drift velocity of the charge carriers is v₁ = 2.7 × 10^-5 m/s. What is the drift velocity of the charges when a current I₂ = 0.5 A passes through a wire, made of the same material of cross-sectional area A₂ = 3 mm²?

A) 8.4 × 10^-5 m/s
B) 6.4 × 10^-5 m/s
C) 1.7 × 10^-5 m/s
D) 3.2 × 10^-5 m/s
E) 2.1 × 10^-5 m/s
