    Interpreting Young's Light Interference Data: Can You Help Me Clear My Doubts?

    Hello! I have done this experiment and managed to find this data: http://puu.sh/bO8TJ/ac3520ec8b.png Am I right for saying that the position that reaches the value of 5 amps are the central bright and the position 220-ish as the 1st bright order and the position 260-ish as the 2nd bright...

    Balanced Three Phase Load System

    Sorry for not using the latex: Calculating total impedance in a phase {\frac{1}{Z_p}} = {\frac{1}{Z_L}} + {\frac{1}{Z_R}} {\frac{1}{Z_p}} = {\frac{1}{754 j\Omega}} + {\frac{1}{3R}} {\frac{1}{Z_p}} = {\frac{-j}{754 \Omega}} + {\frac{1}{3R}} {\frac{1}{Z_p}} = {\frac{754\Omega - 3Rj}{754 j\Omega *...

    Engineering Calculating Power - Simple DC Circuit

    I do agree I need to read the basics again. "OK. That's fine" I'll assume that equations I brought up is correct then. Thank you all for helping me to solve this problem. ;D

    Engineering Calculating Power - Simple DC Circuit

    OH OH OH OH OH LOL LOL Yeah, I messed up XD I realized where I did wrong XD Thank you guys for bearing with me ;D (V2 - V1)/5 ohm = 2 A V2 - V1 = 10 V V2 = 20 V V3 = 0 V Voltage across the constant current source = 20 V with the active sign convention, the power on constant current source is...

    Because the current generated from the constant voltage source would always make it 2A to the opposite side of constant current source. Ka boom.

    Engineering Calculating Power - Simple DC Circuit

    OMG. @256bits V2 = 0 V (V1 - V2)/5 ohm = 2A [KCL] (10 V - V2) = 10 V V2 = 10 V - 10 V = 0 V No voltage across current source. Do we use the generator-load convention to make the 20 W on voltage source to be generating power not absorbing because it's positive? Thank you guys so much :D...

    Engineering Calculating Power - Simple DC Circuit

    1. 10V 2. With using KCL on the node between current source and resistor, I got 10 V across the resistor I don't know why, but I never had problems in solving these kinds of problems, I think I forgot all of the basics because I had a too long vacation :P

    Engineering Calculating Power - Simple DC Circuit

    Oh, I see. V1 = 10V V2 according to KCL ∑I = 0, V2-V1/5Ω - 2A = 0 V2 - 10V = 10V, V2 = 20V V3 according to KVL V2-V3 = V3-V0 20V = 2V3 V3 = 10V Damn, I'm confused :confused:

    Engineering Calculating Power - Simple DC Circuit

    I'm taking reference from the previous question which is shown up there, dunno, I figured it should be the same, or it shouldn't? :o

    Engineering Calculating Power - Simple DC Circuit

    Because of the active sign convention. I did it like I did on the previous question: http://puu.sh/7h4PK.png

    Engineering Calculating Power - Simple DC Circuit

    Well, thank you very much. I must have fail to listen carefully during class while this happens :P But then, Power on resistance = (2A)(2A)(5Ω) = (10 V)(10 V)/(5Ω) = 20 W Power on voltage source = (10V)(2A) = 20 W Power on current source = (-10V)(2A) = -20 W It adds up to 20W, but...

    Engineering Calculating Power - Simple DC Circuit

    I think it's a constant current source. It's always of the same value and stays on the same direction, does it override all other current source though? I have no idea, I may have missed this during class :-\
