# Phasor Diagram that Shows Voltage across the Resistance and Voltage across the Inductance

Question

1. Consider an ac signal applied to a series R-L circuit. Draw a phasor diagram showing the voltage across the resistance, the voltage across the inductance and the resultant circuit voltage.
2. From the above result derive the power triangle
3. Indicate on the diagram, true power P, reactive power Q, and Apparent power S.
4. From the power triangle define power factor.

Summary

This question belongs to electrostatics in physics and discusses about an R-L circuit and to draw a phasor diagram that shows voltage across the resistance and voltage across the inductance and the resultant circuit voltage.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
