Question

Comment on the statement given below:

In self-induction

When the current in a coil is increasing, induced emf opposes it
When the current in a coil is decreasing, induced emf supports it

• A. A is true, B is false
• B. A and B are false
• C. A and B are true
• D. A is false, B is true

Answer 1

The correct option is A A is true, B is false

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 .

Therefore, A is correct option.
