Answer:
The correct option is b
Explanation:
Generally the induced voltage in an inductor is mathematically represented as
[tex]V = L * \frac{\Delta I }{\Delta t}[/tex]
Now [tex]\frac{\Delta I }{\Delta t}[/tex] is the change in voltage with respect to time , when this is zero i.e when the current is not changing(what this means is when current is constant ) the induced voltage becomes
[tex]V = L * 0[/tex]
=> [tex]V = 0 \ V[/tex]
Hence if the current is not changing with respect to time there will be no induced voltage
