Question
The resultant reactance in an $\text{L - C - R}$ circuit is.
✓
Answer
Reactance is the nonresistive component of impedance in an $AC$ circuit, arising from the effect of inductance or capacitance or both and causing the current to be out of phase with the electromotive force causing it.
Therefore, reactance of the $\text{L - C - R}$ circuit is $X_L - X_C.$
Therefore, reactance of the $\text{L - C - R}$ circuit is $X_L - X_C.$
