Calculate the inductance L, of the coil in the circuit diagram shown above
Attached Figure / Diagram
A
3.8H
B
0.6H
C
0.4H
D
0.2H
Verified Correct Answer: B.
Physical Principles & Numerical Solution
XL = \(\frac{V}{I} = \frac{240}{2} = 120\Omega\)
L = \(\frac{X_L}{2 \pi f}\)
= \(\frac{120 \times \pi}{2 \times \pi \times 100}\)
= 0.6H
