Self-Induction
Self-induction is the property of a coil by virtue of which the coil opposes any change in the strength of current flowing through it by inducing an emf in itself.
This induced emf is also called back emf. When the current in a coil is switched ON, then the self induction opposes the growth of the current and when it is switch OFF, then the self-induction opposes the decay of the current.
The inductor has inductance `0.54 H` and carries a current that is decreasing at a uniform rate `(di)/(dt)=- 0.03` A/s, then dt the induced emf will be
Options:
(a) `1.2 xx 10^(-2) V`
(b) `2.2 xx 10^(-2) V`
(c) `1.62 xx 10^(-2) V`
(d) `3.2 xx 10^(-2) V`
