Well ye I took away the 2k resistor, and thats not correct but I still end up whit the same answer when I use the current divider, but its not negative. I = 2.72/6500
So now I_tot = I + I1
This must be the right answer
ok so if I use the superposition method I get this:
First I have this situation

First I replace the current source whit an open circuit and I end up whit this:

hi
I want to find an analytic funktion if Re(z) = 1 - x - 2xy
My initial thought was to set U(x,y) = 1 - x - 2xy and then solve for V(x,y) through
du/dx = dv/dy but it doesnt seem to go as far as im concernd.
Then I thought about the fact that Re(z) = (z + zbar)/2 and then work from...
Homework Statement
I have two parallell plates, they are separated a distance of 1 cm. The potential difference is 10kV. A 0.5 cm thick plastic plate lies between the two plates and has a relative permitivitty of 6. Calcualte E and D in the air and in the plastic plate.
Homework Equations...
I posted a picture at the problem...anyway how do I begin to calculate the electric field? Just to use E = V/d doesnt cut it, I need to incorporate the dielectric constants also

Hi
Two spherical shells where the inner has a radius a and the outer a radius of b. The inner has a total charge of -Q whereas the outer shell has a total charge +Q. The question is to calculate the electric field intensity everywhere in space.
My question is now, how do I choose the limits...
