The RL circuit in the below figure is fed from a constant magnitude, variable frequency sinusoidal voltage source VIN. At 50 Hz, the R and L elements each have a voltage drop Vrms. If the frequency of the source is changed to 25 Hz, the new voltage drop across R is ___________ |
| A. | \(\sqrt{\frac{5}{8}}\) Vrms |
| B. | \(\sqrt{\frac{2}{3}}\) Vrms |
| C. | \(\sqrt{\frac{8}{5}}\) Vrms |
| D. | \(\sqrt{2}\) Vrms |
| Answer» D. \(\sqrt{2}\) Vrms | |
