Engineering 101 - How to find voltage?

Click For Summary
SUMMARY

The discussion focuses on solving a homework problem related to electrical engineering, specifically finding the current (Is) and voltage (Vl) in a circuit. The teacher confirmed that the voltage across a component is 11.90 volts. The student struggles with applying Kirchhoff's Laws and relevant equations to derive these values. The conversation highlights the importance of understanding circuit analysis techniques to accurately solve for current and voltage in electrical circuits.

Homework Statement



niH5T.jpg


The part that I am having problems with is part A, which asks for Is and Vl. I plain and simply can not figure it out. The teach provides answers to check our work, and she said Vl = 11.90 volts. But I don't see how that is the case. I also have no idea how to find Is :(

Homework Equations



I don't know :(

The Attempt at a Solution



I tried using equations to find the change in voltage over a resistor and then use that to find the voltage...Just plain didn't work :(
