Answer 2

Answer:

L = 0.0795 Henry

Explanation:

It is given that,

Current flowing, I = 4 A

Frequency, f = 50 Hz

Power consumed, P = 240 W

Voltage across the coil, V = 100 volts

Let V is the inductance in the coil. It is given by :

$V=I\times X_L$

$V=I\times 2\pi fL$

$L=\dfrac{V}{2\pi fI}$

$L=\dfrac{100}{2\pi \times 50\times 4}$

L = 0.0795 Henry

So, the inductance of the inductor is 0.0795 Henry. Hence, this is the required solution.
