A) The impedance of circuit is \[10\,\Omega \]
B) The reactance in circuit is \[5\sqrt{3}\,\Omega \]
C) The resistance in circuit is 5 Q
D) All the above
Correct Answer: D
Solution :
Impedance \[(z)=\frac{{{v}_{0}}}{{{I}_{0}}}=\frac{220}{22}=10\,\Omega \] Phase difference \[(\delta )=\frac{\pi }{3}\] Power factor \[\cos \phi =\frac{R}{z}\Rightarrow \,\frac{1}{2}=\frac{R}{10}\Rightarrow \,R=5\,\Omega \] \[z=\sqrt{{{R}^{2}}+{{X}^{2}}}\] \[\Rightarrow \,\,X=\sqrt{{{z}^{2}}-{{R}^{2}}}\] \[=\sqrt{100-25}=\sqrt{75}=5\sqrt{3}\]
