Consider the circuit of Figure 6.20. A capacitor with C = 0.25μF is in series with two resistors, R1 = 1500 and R2 = 3500Ω. The peak current through the circuit is
0 = 2 mA, and its angular frequency is ω = 180 rad/s.
(a) Find the voltages on each component (amplitude and phase).
(b) Find the amplitude of the voltage of the source.
(c) Find the impedance of the circuit.
(d) Find the phase between the source voltage and the current.
(e) Write the expressions for the voltage and current as a function of time (amplitudes and phases all included explicitly).
(f) What is the average power dissipated by the resistors?
(g) What is the average power dissipated by the source?
(h) Explain the relationship between the results in (f) and (g).
