<h3><u>Answer;</u></h3>
producing a path for current to flow
<h3><u>Explanation;</u></h3>
- An AC generator is a device that converts mechanical energy into electrical energy using the principle of electromagnetic induction.
- <em><u>Slip rings are two hollow rings to which two ends of the armature coil are connected. These rings rotate with the rotation of the coil. They function to to allow for electrical contact with the brushes.</u></em>
- Slip rings therefore, provide a means for connecting the rotating armature to an external circuit.

Answer:
Force is repulsive
Explanation:
Given data
Current I₁=5.00A
Current I₂=2.00A
Length L=1.20 m
Radius r=0.400m
To find
Force F
Solution
As the force is repulsive because currents are in opposite direction
From repulsive force we know that:
Substitute the given values
