Question

The current does not rise immediately in a circuit containing inductance

• A. because of induced emf
• B. because of high voltage drop
• C. because of low power consumption
• D. because of joule heating

Answer 1

Answer: (B)

because of high voltage drop

$V=L\frac{di}{dt}$
If we have a sudden rise in current, $\frac{di}{dt}$ will be high, which gives high voltage drop across the inductor.

High voltage drop is not possible, therefore, current rises slowly in an inductor.
