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...
Homework Statement
f = 60 Hz
pf = 0.8 (lagging)
Homework Equations
Z(L) = 2 (pi) * f * L
Given z = x + iy
tan(angle) = y/x
pf = cos(angle)
The Attempt at a Solution
I changed the Wye-connected resistors to an equivalent Delta-connected resistors:
The new resistors become 3R in the...
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
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...
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...
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
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...
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 :-\
