Question

Discussion
1- Describe what happens to the current in this RC series circuit as the frequency increases.
Explain in general terms why the observed change should occur.
2- In this experiment, it was shown that the voltage phasor diagram could be obtained by
multiplying each of the impedance phasors by the current in the circuit. If each of the
voltage phasors in the voltage phasor diagram is again multiplied by the current, the
resulting diagram is the power phasor diagram. Using the data in Table 1.1 convert the
current I and source voltage Vs to RMS values. Then draw a plot of the power phasor
diagrams at a frequency of 1000 Hz and another at a frequency of 4000 Hz. Determine
the real power, the reactive power, and the apparent power in the RC circuit at those
frequencies.
