Circuit Analysis - Kirchoff's Voltage Law (KVL), Kirchoff's Current Law (KCL), Ohm's Law (Pt 4)

http://www.FreedomUniversity,TV. The series of videos describes how to combine element and connection equations to find the voltage and current of each element in a circuit. For more videos on these and other topics contact, Professor Santiago at john@e-liteworks.com or visit the above URL.

@drjctu I got -250, but that's because I always set my resistance voltages opposite to my set current direction. So for instance, my 1: +Va - V1 - V2 = 0. And thus my Va is -250. As a matter of fact, all my source's voltajes are of opposite sign as yours. I suppose we're both right in describing the real thing. That's for the video.

@lolliholic256 No need..

[lolliholic256]

why isn't there a node on the bottom between 2A and 5A? confused :s

Thanks for the feedback. I looked at the video and it should be Va=-(-100-150)=250 V. Used Youtube annotation feature so it should point out the error as well as correcting it. Thanks. Dr J

Va should be -(-100) - 150 = -50
