Question
Comment on the statement given below:
In self-inductionWhen the current in a coil is increasing, induced emf opposes it
When the current in a coil is decreasing, induced emf supports it
✓

Answer

  1.  A is true, B is false
Explanation:
In self-induction,induced emf always opposes when the current in a coil is changing either increasing or decreasing.
So, A is true, B is false because when the current in a coil is increasing or decreasing, induced emf opposes it.
