Find the Driving frequency and phase angle for this R-C phasor problem

[QUOTE="Master1022, post: 6161952, member: 650268"] For the [B]phase angle,[/B] I am assuming that means the phase angle between the [itex] V_r [/itex] and [itex] V_c [/itex] phasors. In that case, you know that the currents are the same through both components (as they are in series), then you know how to get the phasor voltages for both components (via [itex] V = I Z [/itex] as you wrote above). I would advise that you let current act as the reference phasor- by this I mean the one that we measure everything relative to, so we put it on the positive real axis on our phasor diagram. So for example, we know the impedance of a resistor is R (i.e. it is a [B]real number[/B]), thus meaning that voltage will just be a scalar multiple of current that is parallel. What can be said for the capacitor? Also, you might think about whether the answer depends on the driving frequency? (BTW, I have just realized that you have calculated tan(phi), so I am guessing that you have this answer already??) For the [B]amplitude of the current[/B]: can you work out the total impedance? If so, can you use [itex] V = I Z [/itex] to solve for I? Hope that is of some use. I was trying to give hints that wouldn't completely spoil the problem for you. [/QUOTE]
