Apparent Power and Power Factor

Introduction: In this lab, we set up the circuit it is given to us and make a minor change of different load resistor and measure its V and I rms.

At first, we calculated various data that was required

The setup.

With 10-ohm resistor, 

With 47-ohm resistor.

With 100-ohm resistor,

Summary: Our calculation was totally off the chart. It is said in the menu that we should use channel 1 to measure the input voltage but we measured voltage across 10-ohm resistor for R_t and used it to measure current and put input in Math channel 1, so we do not think this make much difference. When we were using 10-ohm and 47-ohm resistor in Load impedance, RMS of Voltage and Current did not change much, but when we used 100-ohm resistor, RMS voltage almost halved and current did not change much.
