Question

2. Consider the circuit of Problem 1. Represent the source as the complex voltage \(\Delta V_s = Ae^{+i\omega t}\), the resistor as the impedance \(Z_R = R\), and the capacitor as the impedance \(Z_C = \frac{1}{(i\omega C)}\). (a) Find the complex source current \(I(t)\). What is the (physical) steady-state source current? (b) The series combination of resistor and capacitor has an equivalent impedance whose phase \(\delta\) is a 4th-quadrant angle. Use this fact to write expressions for \(\cos \delta\) and \(\sin \delta\). Then use these expressions to show that the steady-state source current is one of the terms appearing in \(I(t)\) of Problem 1.
