Questions:

1. Is the power supplied by the source the same as that dissipated in the resistor?

2. What do you call the power lost in the inductor? What are the units?

3. What is meant by Power Factor Correction?

4. Construct a Phasor Diagram to represent the source voltage, source current, voltage drops, VR, and VL across the resistor and the inductor. The diagram does not need to be drawn to scale. However, the values of the items represented must be included in the diagram.

5. Can the phase information be obtained from an oscilloscope? Yes No
