Document Summary
Answer each question: (25, for the below circuit, use the superposition theorem to nd the current through the rightmost resistor, i. R: find the thevenin and norton equivalent circuits between points a and b below. B: (25) consider a sinusoidal voltage source of the form v (t) = v0 cos ( t + ) where. Also, nd the voltage drops across each of the circuit elements, vr(t), vl(t), and vc(t). To get full credit, you need to write the complete time domain expressions as well as complex representations for all of these quantities. V out: what kind of a lter is this, find the expression for vout/ vin . Plot the magnitude and phase of vout/ vin as a function of frequency. At a later time t = t0, the switch is moved to position 2. 2: find the voltage drop across the capacitors as a function of time, vc(t).
