Question

At the instant when the current in an inductor is increasing at a rate of $0.0640 A / s$ , the magnitude of the self-induced emf is $0.0160 V$ . What is the inductance of the inductor?

Open in App

Solution

$e = ∣ ∣ ∣ L \frac{d i}{d t} ∣ ∣ ∣ \Rightarrow L = ∣ ∣ ∣ \frac{e}{d i / d t} ∣ ∣ ∣ = \frac{0.016}{0.064}$

$= 0.25 H$
