The switch in Figure P7-68 has been in position A for a long time and is moved to position \(\mathrm{B}\) at \(t=0\) and then to position \(\mathrm{C}\) when \(t=10 \mathrm{~ms}\). For \(010 \mathrm{~ms}\), the capacitor voltage is a sinusoid \(v_{\mathrm{C}}(t)=6.321 \cos [1000(t-\) 0.01)] V.
(a) Suppose the resistance is reduced to \(1 \mathrm{k} \Omega\) and the switching sequence repeated.
Will the amplitude of the sinusoid increase, decrease, or stay the same?
Will the frequency of the sinusoid increase, decrease, or stay the same?
(b) Suppose the inductance is reduced to \(100 \mathrm{mH}\) and the switching sequence repeated.
Will the amplitude of the sinusoid increase, decrease, or stay the same?
Will the frequency of the sinusoid increase, decrease, or stay the same?
