Prelab 2: Sine Waves and the Oscilloscope

1. What is the relationship between peak-to-peak, Vp-p, amplitude, Vp, and root-mean-square, Vrms values?  


2. Find the node voltage measured at the node labeled Channel 2 in figure 2 of the lab in terms of the source voltages v1 and v2.




3. For a circuit like the one shown in figure 3 of the lab, v1 = cos(2p(1000)t), R = 10kW, C is unknown and vo is delayed with respect to v1 by 0.1ms.  Find (assuming circuit is in steady-state):
(a) The phase shift between v1 and vo in radians and degrees,
(b) The value of C for this circuit, and
(c) The expression for vo.
