Physics - EMI/AC Question with Solution | TestHub

Impedance,

$Z=\sqrt{R^2+{\left(X_L-X_C\right)}^2 }$

$\therefore 10=\sqrt{({10}^2+{\left(X_L-X_C\right)}^2}$

$\Rightarrow 100=100+{\left(X_L-X_C\right)}^2$

$\Rightarrow X_L-X_C=0$...(i)

Let$\varphi$is the phase difference between current and voltage

$\tan \varphi =\frac{X_L-X_C}{R}$

$\therefore \tan \varphi =\frac{0}{R}$[From Eq.(i)]

$\Rightarrow \varphi =0°$
