PHY 114 Section 87725 TA: Hank Lamm November 3rd 2011 Abstract: The main goal of this experiment to Investigate the sine wave AC signal from signal generator using the scope and determine the relationships between the rms value and the amplitude of the voltage as well as the period and the frequency of the signal. The following are the results of the lab: T= 10-3seconds‚ Vo=1.4V ‚ 2% discrepancy

voltage from an ac source through a simple resistor. | | | Because the voltage and current reach their maximum values at the same time‚ they are in phase. Ohm’s law and the previous expressions for power are valid for this circuit if the root mean square (rms) of the voltage and the rms of the current‚ sometimes called the effective value‚ are used. These relationships are | | | | Ohm’s law is expressed thus: VR = IR‚ where VR is the rms voltage across the resistor and I is

results. The degrees of freedom were then calculated and an appropriate orthogonal array (L9) was then chosen. After performing 4 trials for each combination given in the L9 orthogonal array‚ the results were interpreted using Minitab. The corresponding Means and Signal to Noise ratio were found and plotted in Minitab. ANOVA tables were also made in Minitab to see which factors affect the results more and which ones can be seen as just an error. From the signal to ratio plots I was able to determine which

analyzed for South China Sea (SCS) and Java Sea (Lat: 9oS~24oN‚ Lon: 99oE~121oE). Monthly mean SST anomalies (SSTA) and synoptic anomalies were produced for the observation of SST variability. Comparison between two strong El Niño and La Niña events of 1997-1998 and 1988-1989 were performed by using synoptic SSTA. We attempted to find out seasonal and monthly mean variation of SST and standard deviation‚ and monthly mean SSTA and their standard deviation. Statistical model was used to find out the best

Towards the Development of a Lodging Service Recovery Strategy John W. O’Neill Anna S. Mattila ABSTRACT. This article presents findings from a survey of 613 hotel guests and indicates that guests’ overall satisfaction regarding service failure and service recovery are higher when they believe that service failure is unstable and recovery is stable. Moreover‚ guests indicate they are more likely to return to the same hotel when they believe that service failure is unstable and recovery is stable

SMART ENERGY METER A smart meter is usually an electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors‚ smart meters can gather data for remote reporting. Smart Meters" usually involve real-time or near real-time sensors‚ power outage notification

was to a digital oscilloscope to measure various signals. The goal of Part 1 was to measure the mean value‚ the frequency‚ peak to peak voltage‚ and the RMS voltage of a triangular input signal. To meet this goal‚ a function generator was used to generate a 1 kHz triangular wave signal with a 1 V amplitude‚ and the oscilloscope was used to measure the values of that signal. Using the oscilloscope‚ the mean value was found to be -37.6 mV‚ the RMS Voltage was 292 mV‚ the frequency was 1 kHz and the Peak
