Question

Q. When a wire carries a current of 1.20 A, the drift velocity is 1.20 x 10^-4 m/s. What is the drift
velocity when the current is 6.00 A?​

Answer 1

Answer:

I=neaV

n=no.of e- per unit vol.

a=area of circular section

e=charge of electron

v=drift velocity

n and e remains constant.

since I=1.20

v=1.20 x 10^-4

neA=I/V

neA=10^4

V=I/neA

V=6 x 10^-4

Answer 2

Concept Introduction: Current is the basic concept of Physics.

Given:

We have been Given:

$i = 1.20ampere$

drift velocity is

$1.2 - {10}^{ - 4} m {s}^{ - 1}$

To Find:

We have to Find: Drift velocity when Current is

$6.00ampere$

Solution:

According to the problem, we know,

$i = neav_{d}$

since Current is directly proportional to everything, therefore, Drift velocity is

$6.00 \times {10}^{ - 4} m {s}^{ - 1}$

Final Answer: The drift velocity is

$6.00 \times {10}^{ - 4} m {s}^{ - 1}$
