Pretty much the title. Just some brain teasers I'm trying to figure out.
I can't think of how a cross section would come into play when it comes to axial loading. Buckling? Since the critical force for buckling is proportional to moment of inertia, so theoretically if I have a high moment of...
I think I see it. iΔ only applies when I have Vs =##\alpha## iΔ. I forgot to think about that iΔ can be ignored.
I want to say use KVL/KCL here but that doesn't seem right to me?
##\alpha## is 400 V/A.
Vs =##\alpha## iΔ , where, Vs = -6V, iΔ= -15mA, so ##\alpha## = 400V/A.
So it sounds like I can't say iΔ (-15mA) is the value of the current going through the dependent voltage source then?
So the main takeaway is that whenever I see iΔ I just have to know that only applies to the dependent voltage source equation (v = alpha* i), and then ignore that for everything else?
For the 6V Voltage source, the power would be negative. P = -i v, where i = 15mA, and v = 6V.
For the...
So I'm confused on a few things about this circuit. I know my math is right (since I got the absolute values correct), but the signs are off since I can't tell when the voltage, current or if the general power equation is positive or negative.
A) So my first question is, where is the current...
