What happens to the inductance when the current in the coil becomes double its original value?(a) Becomes half(b) Becomes four times(c) Becomes double(d) Remains same

Answer» Right choice is (d) Remains same

To elaborate: ϕ is directly proportional to i.

Φ=Li where L is constant of proportionality

So, when current get double ϕ  also becomes double keeping L same.
