Interference of waves:
When two waves of similar amplitude and period traveling in the similar medium superpose, they reinforce each other at one point and cancel at others. This phenomenon is called as the interference of waves.
Suppose the sides of a closed polygam represent vector arrangend head to tail rule , what is sum of these vectors ?
If conductors carries current in similar direction, then force among them will be attractive. If conductor carries current in reverse direction, then force among them will be repul
