Physics Electromagnetic Oscillations and Alternating Current AC Voltage Applied to a Series LCR Circuit
In AC circuits, the relation that holds is \(\rm {Z}=\frac{\mathrm{E}_{v}}{{I}_{v}} \) where.
A. \(\rm {Z}=\sqrt{R^{2}+{X}_{{L}}^{2}} \) in case of a.c. circuit containing R and L in series.
B. \(\rm {Z}=\sqrt{{R}^{2}+{X}_{{C}}^{2}} \) in case of a.c. circuit containing R and C in series.
C. Z = XL - Xc in case of a.c. circuit containing L and C in series.
D. \( \rm {Z}=\sqrt{{R}^{2}+\left({X}_{{L}}-{X}_{{C}}\right)^{2}} \) in case of a.c. circuit containing R. L and C in series.
