Assume an $R C$ circuit with $R=4.0 \mathrm{k} \Omega$ and $C=0.35 \mu \mathrm{F}$ that is connected to an ac generator with an rms voltage of $24 \mathrm{~V}$ and a frequency of $150 \mathrm{~Hz}$ . Will the power factor for this circuit increase, decrease, or stay the same if the frequency of the generator is increased? Explain.
