Question: Suppose we would like to change the phase angle for this circuit to f = -25.0 and we would like to accomplish this by changing

Suppose we would like to change the phase angle for this circuit to f = -25.0° and we would like to accomplish this by changing the resistor to a value other than 175 Ω. The inductor is still 90.0 mH, the capacitor is 15.0 mF, the rms voltage is 120.0 V, and the ac frequency is 60.0 Hz.

(a) Should the resistance be increased or decreased? Explain.

(b) Find the resistance that gives the desired phase angle.
