When a Current I₁ = 1

question 8

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.

• 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
