Unformatted text preview: i. 10^2 x 1 = 100 Hz ii. 10^4 x 1.5 = 15,000 Hz b. Our audible hearing range was less than the average, possibly due to the machines, other noises in the room, or our slight inability to hear. C. RC Time Constant a. Square Wave: R = 10^3 Ω; f = 10^4 Hz; C = 1*10^-8 F; SEC/DIV = 2 x -5 s b. Using the dual trace button: i. .63 (6 Blocks) = 3.8 ii. 2 x 5μ = 1 x 10^-5 μ III. Conclusion This lab has shown that time-dependent voltages vary with time and the type of current. We used electrical current to observe the change in voltage; as shown in the lab, we were even able to use our own voices and observed the voltage output. This lab, though confusing since several new pieces of equipment were used, was helpful in the sense that it introduced new concepts and introductory notions relating to voltages....
