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...
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...
