Three wires meet at a junction. wire 1 has a current of 0.40 a into the junction. the current of wire 2 is 0.65 a out of the junction. part a what is the magnitude of the current in wire 3?

The current in wire 3 is 0.25 A.

Explanation:

It is given that, three wires meet at a junction.

Current in wire 1, I₁ = 0.4 A

Current in wire 2, I₂ = -0.65 A  (out of the junction)

We need to find the magnitude of the current in wire 3 (I₃). Applying Kirchhoff's current law which states that the sum of current in the circuit at a junction is equal to zero.

I₃ = 0.25 A

So, the current in wire 3 is 0.25 A. Hence, this is the required solution.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
