1) Construct the following circuit with appropriate instrumentation to measure
V5, V“ V. and I. Apply 120 V and record readings. Tti'r 2) With your instrumentation in place _1 I

3} On the LabVolt screen open the V‘ o "
Oscilloscope, Phasor Analysis and Metering udndcws. Access and record
your data. 4) Look at the ‘sccpe window and measure the phase shift (in seconds) between
Va and 1. Convert this to degrees and check for appropriatmess. 5) Save your data for V5, VI. V1 and l in a spreadsheet and copy and paste this
intc Excel. 6} Observe the phasor analysis screen and determine if the phascrs are as you
expected them ﬁ'om calculations. 1') Use a print screen to dump the Phasor plot into MS Word.
3) Observe the Metering Screen. Create two new meters to measure power factor and
impedance at the source. 9) Connect the following circuit. Use your
DAI to plot the admittance locus as seen
by the source as you vary the circuit
