You plan to change the frequency of the generator in this circuit to produce a phase angle

Question:

You plan to change the frequency of the generator in this circuit to produce a phase angle of smaller magnitude. The resistor is still 175 Ω, the inductor is 90.0 mH, the capacitor is 15.0 mF, and the rms voltage is 120.0 V.
(a) Should you increase or decrease the frequency? Explain.
(b) Find the frequency that gives a phase angle of -22.5°.
(c) What is the rms current in the circuit at the frequency found in part (b)?
