Homework Statement
10 v, 100 hz goes into a circuit of a 1o resistor, a 1o inductive reactance and a 1o capacitive reactance that are in series.
What is the current. What is the V across the cap.
Homework Equations and the attempt at a solution[/B]
So I know I = V/Z and Z = sqrt( R^2 +...
Hmm, I must have done a sign error or something, this is the work I did for it
I first found IL which was -4 A. Then I did KVL on the left side which I found to be -VC + 7V - V1 = 0. I subsituted V1 to be (-4 A)*(1 ohm) and solved for the rest. Ended up with 11V.
ok I think I got the final answers. Mind checking if I did them right. I was a bit confused on the open circuit at VC, so I wanted to make sure it's correct.
At DCSS, replace inductor with short circuit
At DCSS, replace capacitor with open circuit For t = 0- DCSS, I got IL = 0A and VC = 2V...
Ahhh I see.
So just to confirm... At both t = 0 and t = ∞, the left side is 7V and the right side is 4V.
That makes a lot more sense than what I was thinking.
Ok thanks, so for the t = 0- DCSS, the 2+5u(t) becomes 2v and the 4u(t) becomes a short.
Now for the t = ∞, the 2+5u(t) becomes 7V and the 4u(t) becomes 4V? I was thinking that the 2+5u(t) becomes 2V and the 4u(t) becomes 4V
