When the rms voltages \[{{V}_{L}}\], \[{{V}_{C}}\] and \[{{V}_{R}}\]are measured respectively across the inductor L, the capacitor C and the resistor R in a series LCR circuit connected to an AC source, it is found that the ratio \[{{V}_{L}}:{{V}_{C}}:{{V}_{R}}=1:2:3\]. If the rms voltage of the AC sources is 100 V, the \[{{V}_{R}}\] is close to: |
| A. | 50V |
| B. | 70V |
| C. | 90V |
| D. | 100V |
| Answer» D. 100V | |
