Question

derive the formulae for the force acting between two parallel current carrying conductors.
define ampere on the basis of force ?​

Answer 1

Answer:

Let the distance between the two conductors carrying current I

1

and I

2

be d.

Magnetic field produced by conductor 1 at a distance d, B

1

=

4π

μ

o

d

2I

1

Force acting the conductor 2 placed in this magnetic field F=B

1

I

2

L

Thus we get F=

4π

μ

o

d

2I

1

I

2

L

Force er unit length of conductor 1 f=

4π

μ

o

d

2I

1

I

Now put d=1m, I

1

=I

2

=1A and L=1m

We get F=

2π

μ

=2×10

−7

N

Thus we define ampere as the current flowing in each conductor separated by a unit distance so that one conductor applies a force of 2×10

−7

N on a unit length of another parallel conductor.

Answer 2

Answer:

Answer ⤵️

The unit of electronic current the ampere define using the force between parallel wires shares carrying current the ampere is that current which when following into two infinite possibilities parallel wires 1 metre apart produce of force between them of2×10^7 N/m
