Homework Statement A 2.0 cm length of wire centered on the origin caries a 20 A current directed in the positive y direction. Determine the magnetic field at the point x = 5.0 m on the x-axis. Homework Equations B = uI/2piR The Attempt at a Solution Using the equation above I just...

Alright thank you, sorry for the crappy handwriting ill type it out next time

this is what I was basing myself on if its any help.

Because that would take me the whole night. Sorry both equations are suppose to equal to zero, kirchhoffs current law, right ? For Zc, would it be -200i ? and the voltage as 300 @ 0 degrees ?

Homework Statement Homework Equations impedance equations for capacitors and inductors The Attempt at a Solution I thought something like that might do and then just do a matrix and solve for Va, but I am having second thoughts seems like I am over doing it.

So is it safe to say that the charge from the second point is irrelevant ?

Homework Statement Homework Equations E = kq1q2/r2 The Attempt at a Solution Please correct me if I am wrong but I think it is A. Since doubling the charge, doubles the potential as well, while doubling the radius between the charges would just exponentially decrease the...

Awesomee thanks a lot guys!

Alright so I split the 3 ohm resistor, and then could I add a wire to make the 1.5 ohms resitors parallel to the 3 ohm resistors and take it from there ?

Is it possible to simplify this circuit using just parallel and series definitions ? * A circuit is parallel to another circuit or several circuits if and only if they share common terminals; i.e. if both the branches touch each other's endpoints * Resistors can be connected...
