Question

Calculate inductive reactance of coil in the following figure.

Answer 1

Voltage supply is given as $V=10\sin \left(1000t\right)$
Comparing it with $V=V_o\sin wt$
We get $w=1000$
Inductance of coil is given as $L=20mH=20\times {10}^{-3}H$
Thus inductive reactance of coil $X_L=wL$
$⟹X_L=1000\times 20\times {10}^{-3}=20\Omega$
