Thank you very much, that clears it up for me!

Alright, in the RC circuit link there is an RC series circuit with R = 5 Ohms C = 100 microFarads V = 10V / 60Hz The total impedance is calculated to be 27 ohms and an angle of -79 degrees. The total current is calculated to be 370.5 mA at an angle of +79 degrees. In the RL circuit, R =...

Homework Statement This isn't so much of a problem itself but I found it interesting that on the All About Circuits website, two of the questions give a phase angle for impedance as opposite the angle of current. I understand the current is 90 degrees out of phase with voltage in both RL and RC...

How embarassing...I now see the error of my ways, thank you for revealing this to me. (someone should probably close this thread)

thanks for your comment, but I'm not sure I understand I can see that I skipped a few steps during that process, but I will show how I arrived there x(dv/dx)= (1/v) + 2v dv/dx = ((1/v) + 2v)/x dv=((1/v)+2v)*dx*1/x dv/((1/v)+2v) = dx/x dv*(v+(1/2v))= dx/x Forgive my ignorance, but I fail...

Homework Statement Find the general solution of the equation x*y*(dy/dx)=(x^2) + 3(y^2)Homework Equations The Attempt at a Solution So I start by realizing this is (likely) a homogeneous differential equation, and then rewrite it in the form required: dy/dx = (x/y) + 3(y/x) then, using the...
