A long, straight wire of radius R carries a steady current I that is uniformly distributed through the cross section of the wire

vitfil [10]

Answer:

When $r \ge R$

$B = \frac{ \mu_o * I}{ 2 \pi r }$

When $r< R$

$B = [\frac{\mu_o * I }{ 2 \pi R^2} ]* r$

Explanation:

From the question we are told that

The radius is R

The current is I

The distance from the center

Ampere's law is mathematically represented as

$B[2 \pi r] = \mu_o * \frac{I r^2 }{R^2 }$

$B = \frac{ \mu_o}{2 \pi } * \frac{r}{R^2}$

When $r \ge R$

=> $B = \frac{ \mu_o * I}{ 2 \pi r }$

But when $r< R$

$B = [\frac{\mu_o * I }{ 2 \pi R^2} ]* r$

reasons. 5. Why is the unit of temperature called a fundamental unit? Give reasons. ring derived unit.

Furkat [3]

Explanation:

It doesn't depends upon other.

It have it's own identity.

It's a lot easier to measure temperature than to measure the motion of component particles.
