I have this homework problem in my book, it says:
In the circuit shown in the figure, the current flows in the circuit is 0.644A and the the RMS of the AC source is 100V, calculate the reading of the voltmeter.
I calculated the voltage across the capacitor and the inductor branch and got a voltage of 96.6V. But I said to myself to try to calculate the voltage across the AC source and the ohmic resistance branch thinking that it must have the same value as they are connected to the same two points the cpacitor and the inductor are connected to. And I did this: (Note that Veff is the RMS of the source) I thought that the branch of the AC source and the resistance has the same voltage as the branch of the capcitor and the inductor, but apparently it doesn't, so why? Did I do something wrong? Or what?
